基于子孔径方位特性的穿墙雷达虚拟多视角成像方法
An Aspect Dependence-based Virtual Multi-view Method in Through-wall Radar Imaging
摘要
Abstract
Aiming at the problem of ghosts in the image area caused by the multi-path effect of signal prop-agation in the indoor irregular scene of through-wall radar(TWR),a new method based on impulse radar signal platform frequency domain compressive sensing(CS) framework of multi-path exploitation is pro-posed.Based on the establishment of the multi-path pulse signal vector model in the room,each multi-path component is regarded as a special observation channel,and the aspect dependence(AD) feature is em-ployed between the target and multi-path ghosts to analyze the relevance between the position of target, ghosts and the sub-array.Finally,the multi-path ghosts will be restrained and the virtual multi-view image is achieved by harmonic mean based additive-multiplicative fusion(HMAM).This method overcomes the shortcoming that the computation complexity of time-domain compression sensing in pulse signal is high and the knowledge of the reflecting geometry should be known in advance.Simulations from different sce-narios verify the feasibility and superiority of this method.关键词
