摘要 常用的宽带雷达信号有线性调频脉冲信号、13位Barker码二相编码信号和频率步进信号等。在分析以上三种信号模糊函数的基础上,基于相控阵雷达空时自适应信号处理系统,针对以上三种不同信号的空时自适应处理进行仿真分析;在自适应处理过程中采用对角加载SMI算法,使得自适应系统具有稳健性。仿真结果表明频率步进信号在距离高分辨应用场合中更具优势。 Linear frequency modulation pulse signal, 13 bit Barker code binary phase coded signal, stepped-frequency signal are broadband radar signals. Analyzing ambiguity functions of such three different signals, space-time adaptive processing was simulated based on the space-time adaptive signal processing system of phase array radar. The diagonal loading SMI algorithm was employed to increasing the robustness of the adaptive system. The result of the simulation shows that the stepped frequency signal has an advantage of the high distance resolution applications.
