Low Scattering Performance and Scattering Center Characteristics of Streamlined Space Target

Compared with the conventional cone and cone-cylinder space targets, streamlined space targets (SSTs) have attracted significant attention due to low scattering performance. In this article, a curved surface optimization method for SSTs is presented, which quantitatively demonstrates the radar cross section (RCS) reduction properties of SSTs; then, the location and RCS characteristics of the sliding scattering center on the surface that is unique to SSTs are analyzed; finally, a dynamic echo simulation algorithm is proposed based on scattering center characteristics. The simulation experiment shows that the generated SST echo reflects the characteristics of scattering centers and micromotion accurately, which can provide data for the recognition of space targets.
