Abstract

Abstract

Modeling of radar target scattering center is a key step in radar target characteristic analysis and radar target recognition. The wide application of smooth streamlined structure to radar target brings great challenges to traditional scattering center modeling. This paper focuses on the modeling of the sliding scattering center. Firstly, the position expression of the sliding scattering center is deduced based on the two cases of surface edge scattering and surface scattering respectively. Secondly, a sliding scattering center estimation method based on extended OTSM map is proposed. The location of the sliding scattering center is derived from the projection geometry of adjacent perspectives. Then, combined with the fixed scattering centers obtained by RANSAC algorithm, the complete scattering center model of the target is obtained. The algorithm is verified by the experiment results of the anechoic chamber data, which demonstrate the effectiveness of the proposed method.
