When existing the same frequency radar, in the same area, they interfere each other.
If p.r.f.(pulse reputation frequency)is the same, Interference can’t reject on the screen.
In that case shift the p.r.f. a little may decrease the radar interference.
PRF Fine Tuning:
If radar interference cannot reject completely, it is effective way to shift the PRF.

The rotational speed of inside microwave radiator is possible to change.
The sensitivity of radar are low speed is more higher.
So scanner rotation speed is possible to change according observing range.
Every pulse length can select the Antenna rotation speed.
Short range uses short pulse (SP).
Medium range uses medium pulse (MP)
Long range uses Long pulse (LP)
Shorter range requires the High speed refresh screen.
Longer range requires the Low speed for High sensitivity.

ABOUT THE DATA READ OUT WHEN MEASURE USING EBL /VRM
The RADAR can measure Target position as BEARING(degree°
°°
°) and RANGE(nm).
BEARING is two way to measure.
①
①①
①One is the RELATIV BEARING which is measured from Own ship heading line.
②
②②
②Another is ABSOLUTE BEARING which is measured from the NORTH line
Of cause, ABSOLUTE BEARING is calculated by (RELATIV BEARING+GYRO BEARING).
So, ABSOLUTE BEARING is necessary the signal from GYRO or GPS compass.
☆
☆☆
☆In case of no external bearing signal, display only RELATIV BEARING mode.
☆
☆☆
☆(TT)Target Tracking function and display AIS symbol is necessary the GYRO
or GPS compass signal.
When GYRO or GPS compass signal are received, normally Azimuth is measured
based on from the NORTH(ABSOLUTE AZIMUTH).
This Radar’s scanner microwave BEAM WIDTH is about 5degrees.
So every target echo has more than 5degrees width for bearing direction.
For above reason, In case of read out the target azimuth, set EBL line to the center of the
target echo.
Target echo RANGE is measured by the distance from Own ship for any azimuth.
Target echo size is proportion to pulse length which own ship was transmit.
In case of MEASURE SHORT RANGE ECHO using VRM, set ring to the echo’s nearest
point from Own ship.
At that point is the correct RANGE for any pulse length.

And any time keep displays the plot symbol on screen.
For help the dropped person, anyway navigate the ship to MOB symbol position.

5-4 SETUP THE GUARD ZONE
(WATCH THE TARGET IN ALARM AREA)
Guard zone function detects the echo’s moving in warning area.
Alarm area can set in-alarm, or out-alarm both.
In alarm: Target echo is inside guard zone, generate the alarm sound.
Out alarm: Target echo go to outside of guard zone, generate the alarm sound.
Watching area is setting start point to end point of circle area.
Select alarm condition in-alarm or out-alarm.
＊＊＊＊
＊＊＊＊＊＊＊＊
＊＊＊＊
FOR REFERENCE
＊＊＊＊
＊＊＊＊＊＊＊＊
＊＊＊＊
Guard zone is move accordance with own ship’s movement.
For example, set front side of the own ship, start keep watching, and if ship
is crossing the setting area, automatically generate the alarm.
On the other hand, watch keeping sip is set inside the guard zone, if ship
were go outside the guard zone, automatically generate the alarm.
Crew can realize which ship was moved.
So, it is effective to use as watch keeping the fishing net or buoy.
