The Joint Radar Cross Section Imaging and Inversion Method Based on Modified Backprojection Algorithm

High stealth property is the core performance of modern weapons and equipment. In general, radar cross section (RCS) is used to represent the steal performance. The RCS imaging and inversion play an important role in evaluating the steal performance of modern weapons and equipment. In this paper, the principle of two-dimensional RCS imaging is introduced firstly. Then, the RCS imaging and inversion method based on modified backprojection algorithm is proposed. The joint RCS imaging and inversion method are both verified by simulation experiments. The results show that the proposed method has high accuracy.
