摘要
根据m序列相关函数在非相关点具有恒定值的特性,利用对消方法可降低伪随机码(m序列)调相CW雷达的距离副瓣。实验结果表明,对码长为63 bit的m序列来说,其距离副瓣可降低约38 dB。
Based on characteristics of correlation function of m se-quences. A method is introduced for reducing the value of range side bandof the CW radar with pseudo-random code phase modulation. Experimen-tal results show that the value of range side-band will be reduced about 38dB for 63 bit length of m sequences.
