Abstract

It is extremely complex to detect and recognize space group targets. Aiming to the resolution of group targets with spinning micro-motion, an approach based on range slow-time image is proposed in this paper. Different from the thought of m-D (micro-Doppler) curves separation in other literatures, the "sum function" which is an additive combination of each scatter's range varying function is gained basing on the m-D curves in range slow-time image of broadband radar. Taking Fourier transform to the "sum function”, and then the group targets resolution is realized according to the frequency components of "sum function". The simulation illuminates the feasibility and robustness of this approach.

Key words： spinning micro-motion; group targets; micro-doppler; range slow-time image; Fourier transform
