Abstract

穿墙目标探测是超宽带脉冲雷达在反恐斗争、灾难救援、城市巷战等方面的一个重要应用。SEABED算法是基于超宽带脉冲雷达的一种新型目标定位识别算法,但其不适用于对障碍物背后的目标进行定位的情况。该文在SEABED算法的基础上,分析SEABED算法在穿墙探测中的不足,提出一种新的定位算法使得SEABED算法能够对目标进行定位识别。该算法假设在近场条件下,利用回波时延差的关系曲线求得入射角,从而结合几何关系消除墙体对传播时延和传播路径的影响,将SEABED算法应用于穿墙成像应用中。仿真结果表明,该算法能够弥补墙体对SEABED算法的影响,精确度高,目标定位识别效果好,达到穿墙探测的目的。
