Abstract

This paper shows that the scattered field data collected by using a radar with narrow bandwidth and small aspect angle sector is suitable to fast and handy radar imaging and recognition. For conditions of low-resolution radar a parametric model for 2-D radar target is described according to the theory of electromagnetic scattering and the geometrical theory of diffraction. A high-resolution estimation algorithm to extract the model parameters is developed by building the relation of the scattering model and Prony model. The simulated analysis shows that the accurate extraction of the diffraction coefficient of scattering center is restricted by SNR, radar center frequency and bandwidth
