1. Introduction
1.1 Radar types
Radar Equipment
Use the radar only as a navigation aid. The crucial decisions about navigation must always be made by the operator. Navigating
only by radar can lead to accidents such as collisions or grounding.
There are two technologies that apply to radar, pulse and solid state (Chirp)
Pulse Radar
Pulse radar uses a magnetron to create the transmitter pulse.
It's a cheap and straightforward way to produce a powerful transmitter pulse. The magnetron
must be annealed to work, the filament will weaken after a while and the magnetron must then
be replaced. The service life depends on the method of use and possible vibration.
Solid state radar/ Chirp S-band Radar
The chirp signal is a frequency modulated transmitter pulse. The frequency modulated transmitter pulse goes from 4.6µs, 9.6µs
or 18.1µs depending on the radar range. The frequency of this signal is 3060MHz + 4MHz
The transmitter starts with low frequency then the
frequency increases linearly. In order to utilize the
entire transmitter signal, the receiver has delayed
circuits on the video (radar) signal, mostly on low
frequencies and less on higher frequencies. The result
will be that echoes to one target are detected with
different frequency, but at the same time. When the
signal is summed in the receiver, echoes in the same
phase are summed to one strong echo, while noise is
suppressed. Have tried to illustrate this on the next
page.
The low frequencies are delayed the most and then less delay
at the higher frequency.
The goal of this delay is that reflections from one echo come
out of the receiver at the same time and are combined into
one powerful echo.

JMR-5400 User Manual 20201214 temp 7
Have tried to show this graphically in time axis, the lowest frequencies are delayed the most as it is the one that was sent out first
and goes through all the delay circuits. Higher frequencies are delayed less so that the echoes with different frequency come
through the receiver at the same time and at the end of the receiver are summed and mixed into one strong echo.
The signals is delayed each
time it goes through the 

High frequency
The problem with such a long transmitter pulse is that it is not possible to receive an echo if the pulse is transmitted. Transmitting
the pulse in the longest range will shade out to 1.5Nm. To solve this problem, a short signal is transmitted on one at a different
frequency than the long transmitter pulse. This signal is used to create the radar image close to the boat.
The pulse length of this is 0.07µs - 1.14µs depending on the area of the radar, which is like the transmitter pulse of a magnetron
radar, the frequency of this radar is 3035MHz.
The pulse that changes in frequency 3060 or 3065 and changes ± 4MHz and is 4.6µS to 18.3µS depending on the distance setting
on Radar, Both signals are then used to create a radar image that goes from the center and all the way to the maximum range
1.2 Limitations in radar resolution.
Separation in distance
The radar pulse moves out of the radar at 300m / µS (microsecond).
overall speed is then 150m / µS
If the transmitter pulse is 1µS, two targets must be at distance more
than 150m, then echo number 2 will come as a separate echo and
not as an extension of echo 1. To separate echo, select shorter
transmitter pus.
The differentiating capability of a CHIRP radar depends more on the
narrow bandwidth of the filters in the receiver

JMR-5400 User Manual 20201214 temp 8
Separation in bearing
If there are two echoes next to each other, the radar «beam» must leave the first echo before it hits target no. 2 to be able to
separate the echoes from each other.
Minimum detection distance
If the antenna is placed high, the echo approaching the boat will come under
the radar beam and thus not appear in the radar image. Here comes and goes
the problem of shadow from the hull. IMO is ready in requirements for radar
installation
The antenna must not be mounted so that there is something that shades it at a
longer distance from the boat than:
For boats under 250 m, two boat lengths
For boats over 250m, maximum shade is 500m

JMR-5400 User Manual 20201214 temp 9
Estimated range on radar
Since the radar beam is not normally deflected much, it can be said that the height of the antenna and the height of the target
determine the range (+ that the target gives a usable stable echo)
= 2.23 (√ℎ1 + √ℎ2) Height in meter and distance D will be in Nm
Simple memory rule 10m ant height and 10 m height on the target, then it should be displayed at 15NM.
If the antenna height is 10m and you see a target of 64NM, you can assume that the target has a height above 660m.
Deflection of radar signal
Temperature layers can cause deflections that affect range
Even temperature gives the right beam
Cold air over warm seas can bend the radar beam
Warm air over the cold sea will be able to bend the beam down and you can see echoes "below" the horizon.

JMR-5400 User Manual 20201214 temp 10
1.3 Echo treatment / filtration
NB! In order for the filter to work optimally, the gyro signal should reach 50 times / sec as well as the correct speed indication
from Log and GPS.
Sea noise suppression (STC) and Gain amplification.
These two functions are related to the fact that Gain indicates the maximum gain used and STC reduces this at short range.
Short-range gain then varies depending on how much Sea (STC) is set and up to the maximum gain specified by the Gain button.
Amplification
Diistance
Adjust Gain at long range and use STC / Sea noise to adjust the gain at short range.
When the Sea function is in use, never set the suppression level too high. This may mean that echoes near the vessel are not
displayed. Then it is not only echo from waves that are attenuated, but also echoes from ships and other objects are removed
from the screen. Be sure to use as little Sea as possible.
If this is set to Auto, the radar will adjust the Sea Noise function in 15 ° sectors around the boat, but you have the option to
manually adjust the starting point of sea noise with the SEA button. If you walk in narrow waters and use the Sea damper
function, be aware that the damping can change with the conditions, it is especially important to follow where the landscape
changes sharply.
Rain and snow noise suppression.
When using this function, never set the suppression level too high. This will mean that all echoes, even those that are not due to
rain or snow, can be attenuated so much that they do not appear on the screen.
When using this function, be sure to use the most appropriate noise suppression function
Target Tracking (TT) function
Use target tracking only as a navigation aid. The crucial decisions about navigation must always be made by the operator.
Navigating only by radar can lead to accidents.
Information about tracked targets, such as vector, target numeric data, and alarms may contain errors. Targets not detected on
the radar cannot be displayed or tracked. Navigating only by radar can lead to accidents such as collisions or grounding.

JMR-5400 User Manual 20201214 temp 11
Echo magnification
Echo magnification
Enhance echo is selected level from Off to level3. this makes the echoes a little bigger.
This happens both in distance detection and bearing [azimuth].
For distance, each measuring point is checked and compared with the nearest ones, in the drawing below the measuring point
with echo is shown as X, echo that is magnified is shown with o. If there is no filtering, each measuring point that has data will be
displayed on the screen, this will small noise pulses will be shown in the picture, see line 1/1. By checking several measuring
points against each other, and only showing the result when, for example, 3 of 5 points has an echo signals, a small echo
consisting of three echo points of 5 will be shown as one echo with a size of 5 points, see line 3/5 . Goals with 3 contiguous echo
points will be magnified both ways.
This means that small echoes will increase in percentage much more than large echoes.
For bearing (azimuth), each transmission is checked against the previous one to check if there is a real echo or just a noise pulse.
Echo presentation
When the echo is filtered and is to be displayed on the screen, the presentation depends on how it is to be
displayed on the selected Process function.
Radar echoes are stored in a geographical memory, which is updated using position, course, and speed. With
the help of this memory, depending on which processing is selected, you can filter out unwanted noise such as
sea echoes, echoes that are not repeated at the same geographical position, as well as amplify real echoes that
are repeated at the same position.
. . . . . . . . . . . .
Echoes that are drawn on the same geographical position can, depending on the selected process, see below, be drawn so that
the echo is displayed stronger for each swipe, 3,4, and 5 scan processing. In this way, sporadic echoes will only be displayed with
minimum brightness.

Here, the intensity of the radar echo is built up
per sweep (antenna rotations) so that sporadic

The disadvantage of this filtering is that echoes
from fast boats can be filtered so that they do
not reach full intensity, but they will appear at
low intensity.
