摘要

空间群目标的探测与识别问题异常复杂。文中针对宽带雷达信号条件下的自旋微动群目标分辨问题,提出了一种基于距离慢时间像的群目标分辨方法。不同于其它文献中m-D曲线分离的思路,文中根据宽带雷达距离慢时间像中m-D曲线,求解所有散射点到雷达的距离变化函数的“和函数”,再对“和函数”作傅里叶变换,根据“和函数”在频域的分量实现群目标分辨。仿真实验验证了所提方法的可行性和鲁棒性。

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
