Abstract:

Lots of applications are based on the bistatic radar system for its enhanced radar cross section (RCS) when the transmitter works on the forward scattering area (bistatic angle is larger than 135°). For radar in some practical situation, echoes include scattering signal and incident signal at a considerable range of the bistatic angle. The total field differs with the scattering field in many characteristics like phase, which will have influence on the applications of the forward scatter radar (FSR). The echoes of some FSR objects are simulated when the bistatic angle and distance between the receiver and the object changes. The echoes composition and characteristics are analyzed and the drawbacks of the shadow theory will be listed.
