Chapter 2. How it works
2.1. What is Radar ?
Radar stands for Radio Detection And Ranging.
Radar was developed its principles while World War
II, However It wasn’t invented as echo of
navigation equipment.
2.2. Measuring of ownship
position before Radar being
invented.
Before Radar came, vessel is sailing along the
coastline when fogy day, they’re making noise by
ringing the bell or whistle, fire-arrow etc…
A transmitter emits radio waves, which are reflected
by the target and detected by a receiver, typically in
the same location as the transmitter. This enables a
radar to detect objects at ranges where other
emissions, such as sound or visible light, would be
too weak to detect
2.3. Measurement of Radar
Measurement of Radar is mearued by calculating
of time difference between transmitting signal and
reflected echo.
Radar Frequency speed is recognized that its speed
moves 162.000nm per sec regularly.
Thus, it requires the time to check range of signal
reflected as echo from obstacle & signal transmitted
to obstacle. The echo is entirely coming and going,
it needs to be measured only straightline from
obstacle, which should be 1/2 time.
This radar is calculated automatically.
2.4. Measurement of a Course
One way to measure the distance to an object is
to transmit a short pulse of radio signal
(electromagnetic radiation), and measure the time
it takes for the reflection to return. The distance is
one-half the product of round trip time (because
the signal has to travel to the target and then back
to the receiver) and the speed of the signal.
2.5. Speed of Radar waves &
Antenna rotation
The radar waves to obstacle and returning as
echo should be compared from antenna speed very
quickly.
Then, the first transmitting of very short radar
pulse is returning as echo at the same time its
scanner rotating.
2.6. Radar Display
As it called PPI(Plan Position Indicator), which is
displayed in distance & course from obstacle.
This display is indicated as reverse image being
transmitting ownship position in the middle.
Its course, distance are displayed as echo image
from center of PPI.
Continuous obstacle image is displayed, also
moving of vessel which is transmitting.

영상이 붙었다.
4.3.5. Rain/Snow Removal
(1) If much rain/snow, it is difficult to analyze the wishful target image as the echo by rain/snow clutter
appears on the PPI display.
(2) Turn (rain/snow) to the right to remove the echo image by snow and rain.
Reflected Wave of Rain/Snow Removed Rain/Snow
(Target Retricted, too)
ATTENTION
※It should be always observed by adjusting the optimum conditions.
※If the gain is too low, the targets may not be displayed.
※If too high, it may be an obstacle in observation due to the noise increase on the
PPI display.
ATTENTION
※Too much adjustment of rain/snow removal will restrain the target of ships or
hazards as well as any images by rain/snow. This can be the cause of image
analysis.
※In case of use of rain/snow removal, the optimum conditions should always set up.
