3.3 Radar signal correlation (PROCESS)
There are 3 signal processes; PROCESS 1, PROSCESS 2 and PROCESS 3. The signal processing
consists of residual images processing and signal average processing to eliminate such clutter as sea
surface or rain reflection.
For normal functioning of the signal processing, external signals of ship’s bearing and speed are
required.
Signal process 1 is effective for detecting the ships moving at a speed higher than 15 kn.
Signal process 2 is effective for detecting the ships moving at a speed lower than 15 kn.
Signal process 3 is highly effective to detect buoys such as course indicators and floats. However,
moving ships may disappear.
1
Move the cursor to set value window of [PROCESS] at the upper right part of the screen.
Press [ENT] key repeatedly until the desired value appears.
2
Turn the [SEA] and [RAIN] knobs to adjust the clutter to a dark level not to get in the way of
detecting targets.
•
PROCESS 1:
This is the process to get stable display of targets per every rotation of an antenna. It is effective to
detect moving ships at high speed.
PROCESS 1 is the processing characterized by residual image effect and has also depressing effect
on clutter as compared with input signal.
