Range Compensation (PSRC)

The peak threshold can be adjusted to allow for the

expected change in signal with range. The adjustment

Figure 11: “Smoothing = On” on the left side and “Smoothing = Off” on the right side

is made by dividing the threshold by the range to the

power of the compensation value. 0.0 results in no

adjustment. 1.0 is a linear decrease in threshold with

range etc. The threshold at the centre range is not

adjusted, so the threshold is increased for shorter

ranges and decreased for longer ranges.

Smoothing (PSSM)

The mean range-doppler map can be smoothed with

a 3x3 Gaussian window.

Figure 10: Peak threshold = 400 on the left and threshold = 4000 on the right

Peak Threshold (PSPT)

If a value in the range-doppler map is higher than its

neighbouring values in range and doppler speed (it is

a local peak) and it is more than a specified amount

higher than the exponential moving average (it is a new

signal), it is detected as a peak. The required increase

in signal strength is set using the PSPT command.
