[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
a gain correction value to the "-" side.
[Page 5] [2] PRF
･ Same function as in the TXRX Setting described in "3.8.3 Set Scanner Unit".
[Page 5] [3] Small Buoy Detection
･ Reduces the loss of signal processing during detection of small targets.
OFF: Activates the general signal processing mode.
ON: Activates the small buoy detection mode that reduces the loss of signal processing.
[Page 5] [4] Fishnet Detection
･ Use this mode to detect small targets hidden by sea clutter returns.
･ This function becomes more effective when the AUTO RAIN clutter suppression function is used
together.
OFF: Activates the general signal processing mode.
ON: Activates the fishnet detection mode.
[Page 5] [5] Antenna Height
･ Set the height of radar antenna above sea level.
･ The STC/FTC curve is changed.
Default
Under 5m
5-10m
10-20m
20m Over
or Peak Hold
: Become to the signal processing mode.
: Set the antenna height under 5m.
: Set the antenna height 5m to 10m.
: Set the antenna height 10m to 20m.
: Set the antenna height over 20m.
3-95
is used, noise is hard to disappear. Thus, set
