| 摘 要： | 为提高伪随机码连续波（PRC—CW）雷达性能，讨论了近距离目标干扰抑制方法。在分析了PRC—CW雷达近距离目标干扰信号的基础上，采用了基于最小均方（LMS）算法的自适应对消技术；通过仿真分析合理选择了LMS自适应滤波器的参数，并采用11公司的TMS320C5402定，量DSP芯片实现了自适应对消器。试验结果表明该对消器能抑制近距离目标干扰。

| Abstract: | A method for suppressing the interference of close-in targets for pseudo random code continuous wave(PRC-CW) radar is discussed to improve the radar's performance.According to the analysis of the interference of close-in targets in PRC-CW radar,a least mean square(LMS) adaptive cancellation algorithm is deployed.The parameters of the adaptive filter are selected based on the simulation,and a canceller of the algorithm is implemented with a fixed-point digital signal processor TMS320C5402.The experiment shows that the interference of the close-in targets is suppressed effectively. |
