Simulation Of Airborne Target Imagery - Dependence On Frequency And Bistatic Angle

Simulated signatures of generic airborne targets are presented in this paper. In particular, two-dimensional images of target shapes as a function of frequency and bistatic angle (between the transmitter and receiver lines-of-sight) are investigated. The theoretical model is based on the classical theories of physical optics and diffraction. Coherent radar cross section is first simulated for monochromatic waves. Image response is then obtained by Fourier transforms infrequency and time. Accurate bistatic radar cross section (RCS) is simulated by evaluating both the physical optics and the diffraction components with a uniform asymptotic analysis.
