Abstract

Abstract:

Due to the good performance of anti-stealth, anti-jamming, and anti-destruction, the detection and recognition issues of bistatic radar systems have attracted great attention. In this paper, the micro-motion space targets are selected as the research objects. Firstly, the relationship between the calculated complex radar cross section (RCS) data and the target echoes are analyzed. Then, the difference in polarization reference plane of the simulated radar echoes and the realistic target echoes is pointed out. After that, the modification method is proposed, At last, simulation results are given to validate the presented algorithm. By this algorithm, the polarization characteristics of simulated echoes are realized more consistent with the real received target echoes. This presented technique can be used to provide echo data on the algorithm research of feature extraction and recognition of micro-motion space targets based on bistatic radar.

Key words: bistatic radar, full-polarized, echo simulation, micro-motion characteristic
