Radar Ground Clutter Measurements And Models Part 1 Spatial Amplitude Statistics

At MIT Lincoln Laboratory, we have collected a large multifrequency data base of radar ground clutter measurements from many sites. We employ our clutter data to develop clutter models. Of particular interest to us is the site-specific prediction of PPI ground clutter maps for ground-sited radars, that is, in simulating the spatial variation of ground clutter. This paper describes our measurements, and presents a statistical clutter model for spatial amplitude statistics based on depression angle, terrain type, RF frequency, and radar resolution.
