Abstract

Asteroid detection radar provides scientific data support for inversion of internal address structure and material composition by obtaining the reflection echo of strange medium on the surface and inside of the star. The detection method of asteroid companion determines that radar system can’t extract target echo form strong surface clutter without Doppler information in the detection process. At the same time, compared with Mars radar detection, resource constraints are more stringent, and the resolution are required higher. In this paper, a multi-point and multi-angle long time stepped frequency broadband synthetic detection scheme is creatively proposed, which effectively solves the contradiction between penetration depth and resolution, the SNR is not enough of sigle-pluse, and the extraction of target echo form strong clutter, etc., providing theoretical basis for the design of asteroid detection radar system.
