Compensation of the range resolution degradation in a bistatic scenario and its influence on classification

Automatic Target Recognition (ATR) in a monostatic radar configuration is a well-known problem but ATR in a bistatic radar configuration presents some additional challenges. In this paper we discuss the degradation of the range resolution with increasing bistatic angle and the resulting apparent shortening of the radar target and present a possibility to compensate for this shortening by stretching the range profiles of the target. Furthermore we show the potential of that method to make the classification of bistatic data feasible with a classifier, which has been trained using monostatic data only.
