摘要 设计了一个超宽带噪声穿墙雷达样机,工作频率为350 MHz^750 MHz,既能够获得较好的距离分辨率,又能够保证一定的穿透性和作用距离。采用后向投影(BP)算法对接收回波与发射噪声的互相关信号进行相干成像,实现目标信号的空间能量聚焦。实验结果表明该方法对超宽带噪声穿墙雷达行之有效,能够实现墙壁后面目标的隐蔽探测和成像。 A UWB through-wall noise radar is designed with frequency range from 350 MHz - 750 MHz, which not only satisfies good range resolution but also guarantees certain penetrability and detection range. Back projection （BP） algorithm is used to the cross-correlation signal of the received signal and the transmitted noise signal to obtain the coherent imaging of targets, and their energy focus in space is realized. Experimental results show that this method is valid for through-wall noise radar imaging and targets behind the wall can be detected with covertness.
