摘要
编码信号是多普勒敏感信号,回波多普勒频移的存在会导致编码信号的脉冲压缩性能下降。文中从积分旁瓣比以及信噪比损失两方面分析了多普勒频移对混沌二相码信号压缩性能的影响,并通过仿真验证了分析的正确性。
Coding signal is doppler sensitive,and doppler frequency can cause the decrease of the compression property.This paper analyzes the influence of the Doppler frequency on the chaotic binary codes based on ISLR and SNR loss.The correctness of the analysis is verified by simulation.
