Modeling of varying geometrical scenarios of bistatic radar

In this paper, a bistatic clutter geometrical model is proposed. The model can accurately describe the geometrical relationship between the bistatic radars and the clutter scatterers, and it can be applied in any bistatic geometrical scenarios. On the basis of analyzing the geometrical relationship between the bistatic radars and the clutter scatterers in varying geometrical scenarios, the paper formulates mathematical expressions to describe the geometrical relationship. The method for deducing the expressions is introduced in detail. Finally, the Doppler-azimuth trajectories are provided with to examine the model via four bistatic geometrical scenarios and compared with that of multichannel airborne radar measurements (MCARM). The results prove that the model is accurate.
