[Page 4] [1] - [7] Trails Setting
• Sa e functions as in the Trails Setting menu described in Section 3.8.2. m
[Page 5] [1] Gain Offset
• Corrects gain while the function mode is called.
• Since the displayed noise level varies depending on the combination of the video process mode
and the interference rejection level, gain needs fine adjustment for always obtaining the highest
level.

• The gain correction function saves the correction value set by the gain adjust in each function
mode, so it can obtain the highest gain without the gain adjust being operated when the function
mode is changed.
• To set high gain, set a value on the “+” side.
• To set low gain, set a value on the “-” side.
• When the radar interference rejection level is increased, the noise level is lowered. Thus, set a
gain correction value to the “+” side.
• When the video process mode 3Scan CORREL , 4Scan CORREL , or 5Scan CORREL is
used, the noise level is lowered. Thus, set a gain correction value to the “+” side.
• When the video process mode Remain or Peak Hold is used, noise is hard to disappear.
Thus, set a gain correction value to the “-” side.
[Page 5] [2] PRF
• Sa e function as in the Pulse Repetition Frequency described in 3.8.3. m
[Page 5] [3] Small Buoy Detection
• When the automatic sea clutter suppression function is used, this mode is used to process signal
for detecting small targets.
s
Off : Activates the general signal processing mode.
On : The signal processing mode for detecting small targets.
[Page 5] [4] Fishnet Detection
• Use this mode to detect small targets hidden by sea clutter returns.
• The simultaneous use with the automatic rain / snow clutter suppression function will increase
effects
.
Off : Activates the general signal processing mode.
On : Activates the fishnet detection mode.
[Page 5] [5] Antenna Height
• Set sea level.
the height of radar antenna above
• T STC C curve is c
he /FT hanged.
-5m : Set the antenna height under 5m.
5-10m : Set the antenna height 5m to 10m.
10-20 : Set the antenna height 10m to 20mm .
20m- : Set the antenna height over 20m.
