TECHNICAL DESCRIPTION
2.1 GENERAL
The theory of operation for the RADAR 1000
MK II is presented here with descriptions
following the functional block diagram circuits.
2.2 SCANNER UNIT
The scanner unit consists of the RF PCB radiator, the motor, radiator rotating mechanism,
bearing reset assembly, and the transmitter/receiver unit. These components are all housed within
the 12.2" radome. The functional Block Diagram appears in Figure
2.
2. 2. 1 RADIATOR
The RF PCB radiator forms the main RF transmitting beam for the radar transmitter and
becomes the receiving antenna during the receive cycle. The beam formed by the patched array
styled PCB at half power points is 7° horizontally and 30° vertically, be direction of the beam
(maximum radiated power) is essentially perpendicular to the radiator surface.

2. 2. 2 RADIATOR ROTATING MECHANISM
The mechanical coupling between the PCB radiator assembly and the motor is effected by a
reduction drive gear. The antenna motor normally rotates the radiator at approximately 32 rpm.
2. 2. 3 MOTOR
The antenna drive motor is used stepping motor. When radar is stand-by mode, J3-l, 3, 4, 6 are
+12V. When Transmitter mode, output
of IC6-12 is changed 136. 5 Hz to 256 Hz at first 7 step.
After 7 steps, output
of IC6-12 is stable at 250 Hz.
The waveform
of J3-1, 3, 4, 6 are as follows:
J3-6
J3-1
J3-4
J3-3
2. 2. 4 BEARING RESET SWITCH
1 3. 5 V
1. 5 V
The bearing reset switch, or otherwise referred to as the "heading reference switch", produces the
signal to reset the scan converter circuitry
to 'O" when the permanent magnet fitted on the main gear
passes across the reed switch
SlOl. The reset signal (BZ) is sent down to the bearing reset circuitry
in the display unit and synchronizes the scanner position to the display sweep. The BZ signal is sent
down to the display together with the Tune indication signal at J2-6.
2.3 TRANSMITTER
The transmitter consists
of the solid state modulator circuits, the power supply, and the 1. 5kW
magnetron.
A. Modulator
A solid state type pulsar design is used by the modulator and primarily consists
of a pulse
generator circuit, power MOSF'ET switch, and pulse transformer.
When setting the X-MIT/STBY key on the control panel at the display unit
to "ON", the
transmitter trigger pulse is sent via the inter unit cable from the transmit trigger generator circuit
in the display unit
to the J2-2 in the modulator.
The switching regulator power supply provides +250Vdc to charge the capacitor (C39).
In
addition to the high voltage for the modulator, the power supply also provides the magnetron
heater voltage (6Vdc) and the operating 12Vdc for the trigger circuits and display unit.
5/34

Generally the pulse width of the pulse generator circuit is controlled by the range key selectors on
the front panel at the display unit. Three different pulse lengths: 0.08usec, 0.3usec and 0.8usec (in
accordance with the range scale) can be provided. The pulse repetition frequency (PRF) always
changes automatically
to match the selected operating pulse length (See TABLE 1 ).
Upon receiving the positive trigger pulse, TR5 generate a differential waveform at C35, R39-R44
setup the discharge period of this waveform
to generate a short (80ns), medium (300ns), or long
(800ns) gate to ICl-6. The pulse is amplified and applied to the gate
of TR14 that will conduct for the
selected pulse length drawing current through the primary
of the Pulse Transformer (T2) generating a
1. 85kV pulse to the magnetron cathode.
TABLE 1 RANGE, PULSE LENGTH, AND PRF RELATIONSHIPS
Range Pulse Length PRF
0.125, 0.25, 0.5, 0.75 nm 0.08us 2250 Hz
1, 1.5 nm 0.3us 1200 Hz
3,
6, 12, 16 nm 0.8us 600Hz
RECEIVER
The receiver circuit consists of the passive diode limiter, the MIC Front End and the Receiver IF
circuit.
The MIC Front End
(ElOl, NJT1967) device consists of the single balanced mixer, and the local
oscillator. The received radar echo signals at 9445 MHz are then sent into the single balanced mixer
of the MIC. The MIC Local Oscillator, tuned by the adjustment of the operator's Tune control on
the display unit front panel to be
60 MHz higher than the magnetron's operating frequency for
maximum target detection, is also fed into the single balanced mixer. The single balanced mixer
output
of 60 MHz echo signals is then coupled into the 60 MHz IF amplifier.
RECEIVER CIRCUIT
The Receiver circuit includes the 60 MHz IF amplifier, bandwidth control circuits, video detector,
tune indicator circuitry, the MBS amplifiers and the video output circuit.
IF Amplifier Circuit: The IF amplifier consists oflow-noise gain controlled transistor amplifier
TR15 and gain controlled IC amplifiers IC9 with bandwidth selector and IClO.
TR15, IC9 and IClO are controlled by the gain and STC control signals generated by the display
unit. Maximum gain is obtained when the voltage level at IC9-5 and ICl0-5 reaches 4 volts.
The band width selector
ICl and TR15 enables to change load resistor so the receiver has either a
10 MHz or a 3 MHz bandwidth characteristic. The selection depends on the pulse length selector
signal (PW).
When +6V at J2-7 is present, the base voltage of
TR16 and TR25 will be +12V volts. In this
condition, the pulse length in operation is 0.08us and the bandwidth
of the receiver is widened to 10
MHz. When pulse length are other than 0.08us, the base
of TR16 and TR25 will be 0V, the
bandwidth will become narrow at 3 MHz.
6/34

VIDEO DETECTOR CIRCUIT
The video detector circuit is
ICl 1 operate as a video detector to remove the 60MHz IF
component from the incoming signals. The output signals on ICl 1-12 are inverted to negative going
pulses and fed
to the video output circuit.
VIDEO OUTPUT CIRCUIT
The video output circuit consists
of emitter follower TR18. The emitter follower operates strictly
as an impedance transformer
to drive the 50 ohms coaxial cable which carries the video signal to
the display unit.
TUNING INDICATION CIRCUIT
The tuning indicator circuit consists
of amplifier TR19, detector TR20, and emitter follower
TR21, 22. TR21 charges Cl 10 to the detected signal voltage. This voltage is sent to the display unit
as a tuning indication voltage via buffer amplifier TR22, with bearing reset pulse. The range
of the
tuning indication voltage varies normally between +5V (detuned) and 1V(tuned in long pulse).
POWER SUPPLY
The power supply converts the ship's mains to necessary DC voltages
to operate the radar system.
These output voltages include regulated +12VDC, +6VDC, and +250VDC. The AVR converter
consists of IC2 and IC3 as well as TRl and TR2. The RVl is normally set by monitoring the
+12VDC output at
TPl and adjusting for +12VDC±0.1VDC with a volt ohm meter.
7/34

2.4 DISPLAY UNIT
The display unit normally contains the Main Control PCB, the Power Supply PCB, the LCD
nodule and the Control Panel PCBs.
2.4.1 SIMPLIFIED BLOCK DIAGRAM
FIG. 2 shows the fundamental circuits of the display unit
in a simplified functional block diagram.
Most system operations within the display unit occur primarily on the Main Control PCB.
It is on
this PCB that most
of the signal processing takes placed. The following is a brief description of the
main circuit functions
of the display unit.
2.4.2 MAIN CONTROL PCB
2.4.3 VIDEO INPUT CIRCUITRY
The incoming video signals from the receiver in the scanner are first routed through the FTC
circuit components consisting
of CD2 and C14. The diode CD2 controlled by the voltage supplied
from ICl0-11 which is determined by the front panel RAIN CLUTTER Control.
2.4.4 AID CONVERTER
The video signals from CD2 and C14 are fed
to an amplifier TRl and TRl output video signals
are converted to digital pulses by 3 comparator ICs IC12, 13, 14. The digital video output
is then
sent
to the system control LSI 1C6.
2.4.5 SYSTEM CONTROL LSI
The system control LSI 1C6 contains video processor, video buffer memory, scan converter, PPI
video memory control circuit, various clock input and output circuit, LCD drive signal generator,
and system control signal generator circuit.
2.4.6 PPI MEMORY AND GRAPHIC MEMORY
The processed video signals are stored in the buffer memory
of the system control LSI, and then
read out on the bearing pulse timing. The buffer memory output is fed
to PPI memory 1C9 followed
by the scan converter data onto its address pins.
And also graphic data from main CPU and GDC are stored in the graphic memory 1C7 and 1C8.
1C7, 1C8 and 1C9 are 64K x 4 bit DRAM. The output data from DRAM are fed to the LCD drive
signal timing are controlled by GDC and LCD drive signal are fed to the LCD unit via output buffer
1C21.
8/34

2.4.7 MAIN CPU CIRCUIT
The main CPU circuit consists
of CPU IC4, RAM IC2, and ROM IC3. The main CPU control's
all
of the radar system with GDC and system control LSI according to the front panel key output
and the data from the other nay-aid unit. The tuning voltage and gain STC signals are generated by
the
DIA converter ICl0 outputs which are contrived from CPU.
2.4.8 OPTIONAL INPUTS
The RADAR 1000 MK II can receive various input signals from Nay-aids and compass. 10 more
than one data type is present
at the radar inputs (for examples; compass and NMEA) a system
priority has been established in the radar's software to respond
to the inputs in driving the features.
The assigned priorities are set in this manner:

TROUBLE SHOOTING
3. TROUBLE-SHOOTING GUIDE
While the RADAR 1000 MK II is highly reliable systems, early signs and detection of
component fatigue can sometimes be spotted during regular operational checks.
When a problem is observed, corrective service should be arranged to avoid failure at critical
tines at sea. In some cases, problems nay be cleared by a system master reset.
3.1 MASTER RESET
The first step in attempting
to clear a problem associated with the general operation of this
Radar is to perform a MASTER RESET. This function will clear the Radar's memory and will
return it to its factory settings.
It may then be necessary to make the INITIAL SETTING and to
re-enter the parameters previously established by the operator.
CAUTION
In making checks, be alert to the high voltage points existing throughout the equipment.
3.2 RESET
This reset will clear the radar's memory except INITIAL SETTING. This can be done by
pressing the
EBLNRM key and while holding, then turning the power on. This should be
performed anytime a component or PCB within the radar is replaced.
3.3 FUSE
A fuse seldom blows out without some cause. Even if a fuse
is merely replaced and does not
blow again, it still may be necessary to make further checks
of the circuits associated with the
fuse.
TABLE 3-1 shows a table
of fuses employed in the equipment.

3.4 FAULT FINDING PROCEDURE
Often the display on the LCD can help indicate which major circuit is at fault.
It may be
quicker to check-out the equipment according to the trouble shooting guide that follows TABLE
3-2.
In general, the common causes
of trouble frequently encountered include abnormal resistances,
intermittent variable resistors, and switches.
In the following fault finding procedure, it is assumed that only a VOM is available; the use
of
an oscilloscope amplifies the procedures and may prove necessary in some cases.
TABLE 3-3 is the troubleshooting guide and check-out procedure, TABLE 3-4 shows typical
voltages and remittances at significant points throughout the equipment. The internal resistance
of the tester used in measurements was 20kO/VDC, 8 kO/VAC.

SECTION 4
MAINTENANCE
4.1 GENERAL
It is necessary to perform the maintenance services listed below to keep the RADAR 1000 MK II
in good working conditions. Proper maintenance of the RADAR 1000 MK II minimizes the
possibility
of machine failures. The maintenance operations that are common to all components of
the RADAR 1000
MK II is listed below.
(1) Cleaning
Remove dirt, dust, or water-spray from the RADAR 1000 MK
II enclosure and keep it as
clean as possible. Use a dry lint-free cloth.
(2) Screw inspection
Check the screws used to assemble and secure the components of the RADAR 1000
MK II
for loose connection.
(3) Cabling check
Check the cables connecting between the components (between the scanner unit and
display unit, display unit and power supply, and display unit and optional devices) for poor
connection.
CAUTION
When servicing the RADAR 1000 MK II, be sure to turn it off to prevent electric shock.
If a rectifier unit is used, in particular, turn off power to the display unit. Note that
voltages from the rectifier unit are always present even
if the radar is stopped.
4.2 SCANNER UNIT
When inspecting the scanner unit
of the RADAR 1000 MK II, be sure to turn offpower to the
display unit. Keep watches or magnetic cards away from the modulator block as it contains a
magnetron having a strong magnetic force.
4.2.1 Radome Scanner Unit
(1) Radome
A radome surface contaminated by smoke, dust, or paint would cause attenuation or
reflections of radio waves, resulting in reduced radar performance. Periodically check the
radome scanner unit. If it proves dirty, wipe the radome surface with a soft lint-free cloth
moistened with alcohol or damped cloth.
*Never use solvents such as thinner, gasoline, benzene, trichlene, and ketone.
(2) Lubricating gears
Check the mounting bolts for loose connection occasionally.
4.3 DISPLAY UNIT
4.3.1 Cleaning the Screen
Dust on the LCD would reduce the transparency and make the video image dim. Wipe the screen
surface with a soft lint-free cloth (made offlannel or cotton). A cloth moistened with an
antiseptic agent would cause little problem. When using it, wipe softly; never rub the screen
surface with force.
