摘　　要：穿墙雷达作为一种便携式侦测雷达,可应用于背景各异的环境中。在不同的场合,产生的与目标信号相随的其他非期望信号也不尽相同。首先分析了对目标识别有影响的各种非期望信号,然后对其中影响较大的收发天线直接耦合信号和天线背向信号做了实验研究,依据产品设计的准则,就如何在产品结构设计中使用、取舍实验数据做了阐述,为本类或相关产品的设计提供借鉴。The through-the-wall radar as a portable surveillance radar can be applied in the environment with various backgrounds. In different environments,the unexpected signals generated with the target signal are different. All kinks of the unexpected signals affecting the target identification are analyzed. The experimental research was carried out for the direct coupling signal of the transceiving antenna and backward signal of the antenna. According to the criterion of product design,how to use and choose the experiment data in product structure design is elaborated,which provides a reference for the design of the same-class or relevant products.
