穿墙雷达目标定位新方法

New Method for Target Location Using Wall-Penetrating Radar

针对墙体参数不确定性问题,提出了一种雷达目标定位新方法。采用不同的收发天线队列校正了由于墙的厚度及介电常数模糊时所产生的目标位置移动的影响,对于每一种结构的天线队列,可获取当墙体参数变化时目标位置改变的轨迹,目标真实位置可由不同轨迹的交点得到。仿真结果验证了方法的有效性。

According to wall parameters inaccurate,a new method for target location is proposed.The algorithm corrects the shifts of target positions due to ambiguities in the wall thickness and dielectric constant using different transmit and receive antenna arrays.For each antenna array,target trajectory is generated using different wall parameters.The intersection of different trajectories is the true target position.The simulating results demonstrate that the method is efficient.
