Note:
- B.W (Band Width):
IF frequency: Receiving bandwidth of 60 MHz.
- PRF (Pulse Repetition Frequency):
The Repetition Frequency is not constant to avoid Radar interface from other radars.
The Jamming range is approximately± 10 % of the Repetition Frequency. When the
Antenna is stopped, the Repetition Frequency is constant.
- ARPA 32NM:
The Repetition Frequency is changed when the ARPA tracking distance is set to
32 NM on [Menu] -> 0 -> 6 -> 9: MAX RENGE.
- 2nd: Repetition Frequency of the 2
nd
trace mode
The Repetition Frequency is changed when the setting on [Menu] -> 1 -> 1: 2ND
ECHO REJ is ON.
