Abstract :
In this paper, a complex exponential model is used to describe the local partial Rayleigh or resonant response at first. Then the multiple frequency response equation of radar target is established. A FFT based strong scattering neighboring range area superresolution algorithm is used to obtain the so-called quasi-two-dimensional image of local spacial eigen-width vers radial range length. The imaging method is more effective than the conventional one-dimensional FFT algorithm which is used to obtain only range profile. Experimental data prove the effectiveness of the presented imaging method
