通过对几种脉冲调制算法的比较，分析了各种算法的优缺点和适用范围，并在原算法基础上加以改进，提出了一种新的脉冲信号调制分析方案：针对不同的信号采用不同的算法。计算机仿真结果表明：此方案识别信号能力强，在较低的信噪比下具有很好的效果。

In this paper, several algorithms of pulse modulation are compared. The advantages and disadvantages of each algorithm are analyzed including their application range. Then some methods are improved basing on the original algorithms. This paper also presents a new modulation analysis scheme of radar pulse signal: different algorithms would match different modulated signals. Simulation results show that this scheme is successful to identify signal modulation,especially in low SNR.
