This paper shows that the scattered field data collected by using a radar with narrow bandwidth and small aspect angle sector is suitable for fast and handy radar imaging and recognition. Based on the conditions of low-resolution radar, a parametric model for the 2D 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 the scattering center is restricted by SNR, radar center frequency and bandwidth.
