摘要

为了抑制后向散射信号，提高水下目标的分辨率，研究了3种不同的调幅方法。它们是一般调幅、法布里-珀罗调幅和双余弦叠加调幅。通过仿真结果对比，双余弦叠加调幅对后向散射信号的抑制效果最好，目标反射与后向散射信号的峰值比接近于1。

Comparison of Amplitude Modulated LIDAR System Underwater Detection

In order to suppress backscattering signal and improve resolution of underwater target, 3 different amplitude modulation methods are studied. They are general amplitude modulation, Fabry-Perot amplitude modulation and dual cosine superimposed amplitude modulation. by comparing the simulation results, the dual cosine superimposed amplitude modulation gets the best effect on suppressing backscattering signal and the peak ratio of target reflection and backscattering signal is almost 1.
