Model comparison of bistatic radar clutter

Bistatic radars are parts of coherent multistatic radar systems for air targets positioning and tracking in various systems including the Air Traffic Control. The signal processing in the bistatic radar invariably encounters with a competitive signal, reflected from terrain objects - the land clutter. In this paper a research in the area of bistatic radar clutter modeling is presented. After the bistatic clutter scenario is defined two land-clutter models, based on a common general geometry are described. The bistatic radar clutter power equation derived here ([9]) is used for computation of interesting parameters like a bistatic radar effective clutter cross section, a total clutter power and a clutter reflectivity. In the end the two models are compared with actually measured bistatic radar clutter with use of a real terrain profile around the radar.
