Clutter Modeling and Characteristics Analysis for Bistatic SBR

In order to analyze clutter characteristics and develop clutter suppression method, clutter modeling is very important. In this paper, we introduce the clutter modeling method of bistatic space-based radar (SBR) and obtain the analytic resolution of the clutter isorange contour in a range gate. Besides, the Earth´s rotation effect is taken into account and the modification to Doppler frequency is derived. Finally, we plot clutter angle-doppler traces based on the modeling Finally, we plot clutter angle-doppler traces and discuss the clutter characteristics for different bistatic geometries.
