摘要

众所周知的Lewis-Kretschmer P4多相脉冲压缩码是基于采样线性调频相位的低旁瓣、多普勒容忍码。本文讨论并展示了如何通过应用不同的加权技术及其权衡来大幅减少副瓣。并与非线性啁啾P(n,k)多相码进行了比较。

Sidelobe reduction techniques for polyphase pulse compression codes

The well known Lewis-Kretschmer P4 polyphase pulse compression codes are low sidelobe, Doppler tolerant codes based on sampled linear FM phases. This paper discusses and shows how the sidelobes can be substantially reduced by applying different weighting techniques and their tradeoffs. Also, a comparison is made with nonlinear chirp P(n,k) polyphase codes.
