中文摘要:在脉冲压缩雷达中发射信号的选取至关重要,通常采用调频信号和相位编码信号。伪随机序列中的m序列是典型的二相编码信号,具有类似白噪声的性质,周期且有规律。文中对m序列的自相关和互相关特性进行仿真,并结合实际工程应用给出了具体的生成方式。通过具体参数的设定,达到工程应用目的。最后结合实际应用给出m序列在雷达中脉冲压缩处理流程,实践证明在工程中取得良好的应用效果。

Study of m Sequence in Pulse Compression Radar
Abstract:The selection of transmitting signal in pulse compression radar is very important, FM signal and phase coded signal are usually used.The m sequence in pseudo-random sequence is a typical binary coded signal.which has similar white noise properties, periodic and regular.In this paper, the self correlation and cross-correlation characteristics of m sequences are simulated, and give generation mode with engineering application.Through parameter setting, achieve the purpose of Engineering application.Finally, the application of m sequence in the radar pulse compression processing flow, practice has proved good application effect in engineering.
keywords:m-sequence  autocorrelation  auto-correlation  pulse compression
