Micro-Stagger
Refer to the source file rvp8main/site/demostag.c, which contains
demonstration code for building custom trigger timing within a new major
mode. A special "micro-stagger" trigger generator is implemented in
which the trigger PRT varies a tiny amount (a few microseconds) from
pulse to pulse. This causes multiple trip echoes to become incoherent when
viewed relative to the first trip Tx phase, thus providing a very simple
method of "whitening" the Doppler signature from range aliased echoes.
The code consists of two parts:
- initMajorMode_stag—The major mode initialization routine is a
direct clone of the FFT code from rvp8main/open/mt_fft.c. The only
