摘　　要：根据超宽带雷达目标特性建立了人体探测模型,并利用互补序列码编码的超宽带脉冲串信号对人体模型进行探测仿真。通过对比编码信号与非编码信号的探测结果和不同信噪比下互补码的探测结果,得出经互补序列码编码的超宽带雷达脉冲信号具有很好的抗噪声能力,是超宽带搜救雷达发射脉冲串的理想编码方式。According to the characteristics of the ultra-wideband （UWB） radar target, a exploration model of human body is built, and UWB-pulse coded by complementary sequences is used to detect it. After comparing the detecting outcomes of the signal coded by complementary sequences and the common pulse signal, and comparing the complementary sequences coded UWB-pulse＇ s detecting outcomes in different signal-noise ratios, this paper comes to the conclusion that the UWB-pulse coded by complementary sequences has a good effect on anti-noise and it is the ideal coding way in UWB search and rescue radar emission pulse signal＇s coding method.
