Bistatic model scattering response analysis and its application

Model scattering response (MSR) matrix is presented to describe bistatic radar cross section(RCS) based on the moment of method. Fourier transform relationship between the two can be obtained by incident and scattering plane wave expanded as Bessel series summation. MSR matrix is low-pass band-limited, reciprocal symmetry and diagonal sparse approximately because of base function characteristic. MSR matrix is independent with the observation angle to the radar target, which is of great importance to target recognition. Fast algorithm of bistatic RCS can be implemented by the characteristic and fast Fourier transform.
