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 paper, 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 micro-motion accurately, which can provide data for the recognition of space targets.
