Range averaging and clutter microsuppression

Range averaging can be performed over 2, 3, ..., 16 bins. This reduces the number of bins in the final output to save processing both in the RVP10 and in the host computer.

This is accomplished by averaging the T0, R0, R1 and R2 values.

At the user's option, the range averaged data can be restricted to include only those bins which have an estimated clutter-to-signal ratio that falls within the CCOR threshold interval.

By excluding isolated point clutter targets from the range average the sub-clutter visibility of the averaged data is increased. Specifically, the Doppler test that is applied to each bin in order that it contribute to the overall sum is:

$10 log ⁡ R 0 − 10 log ⁡ T 0 > C C O R t h r e s h$

The total power T0 is conserved after the exclusion of the isolated point clutter targets.
