On the cancellation of bimodal clutter in Doppler-ambiguous radar
Abstract
The purpose of this paper is to describe and evaluate the MTI techniques that result to be effective against 'bimodal' clutter, i.e., two clutter spectra (e.g., from land and rain/chaff) at different average Doppler frequencies in the same resolution cells. Ground based, Doppler-ambiguous, staggered-PRF radar are considered, which is the case of most civilian and military long/medium-range surveillance systems. The evaluation tools, both analytical and simulative, are also described: these allow comparison of the actual performance with those predicted by mathematical models.
