Abstract

Through-Wall Imaging Radar (TWIR) can reconstruct targets which are concealed behind the wall, so it is highly desired in antiterrorism, hostage situations and other fields. To detect, track and locate personnel targets behind the wall, the TWIR must have the ability of high data frame rate and fast imaging speed. In this paper, we analyze the imaging algorithm for two dimensional multiple input multiple output (MIMO) TWIR. To satisfy the real-time requirement of TWIR applications, we design a parallel realization method based on TMS320C6678. Experimental results show that this parallel method can adequately fulfill the real-time requirements.

二维MIMO穿壁雷达中运动目标成像的并行实现
通过墙成像雷达(TWIR)可以对隐藏在墙后的目标进行重建,因此在反恐、人质劫持等领域具有很高的应用价值。为了检测、跟踪和定位墙后人员目标,TWIR必须具有高数据帧率和快速成像速度的能力。本文分析了二维多输入多输出(MIMO) TWIR的成像算法。为了满足TWIR应用的实时性要求,设计了一种基于TMS320C6678的并行实现方法。实验结果表明,该方法能很好地满足实时性要求。
