5. Zero position offset
Origin EL position offset correction [deg]:
Setup an elevation offset from horizontal level.
Measure the elevation angle after antenna
initialization and set the offset field.
AZ offset to north:
Setup an azimuth offset angle clockwise from origin of
radar.
e.g.: The azimuth origin of the radar is 45 degrees
(measured value) from north. This means 315
degrees difference from north to the azimuth origin.
The value to input into "Azimuth Offset" is 315
degrees.
To clarify it is set as a positive degree offset from
north to the azimuth origin.

7. TX
PRF pattern: Select PRF pattern from 1 to 3. Details are written in Table 2.7.
Pulse set:
Select pulse number pattern from 1 to 8 by clicking [...]
button.
Setting values will be adjusted automatically by using
noise measurement. Also values of A-threshold could
manually change.
・ PRF 1 [Hz] is using a short cycle for dual cycle signal processing.
・ PRF 2 [Hz] is using a long cycle for dual cycle signal processing.
・ A-threshold (pulse 1) [dB] is P0N.
・ A-threshold (pulse 2) [dB] is Q0N.
Note: A-threshold is to eliminate a background noise of received signal.
P0N: Sequence of pulses without modulation (CW) used for short
range detection
Q0N: Sequence of frequency modulated pulses used for long range
detection.
Note: Click [STBY] to select a pulse set, and it is necessary to click [OK] button after every changing a
parameter to reflect.
IF cable length [m]:
Enter the length of signal cable between Antenna Unit and Signal Processing Unit.
