跳频编码脉冲信号是一种新的脉冲压缩雷达信号形式，极具研究价值。模糊函数是设计和研究雷达信号的主要数学工具。跳频编码脉冲雷达信号模糊函数的计算十分复杂，模糊图绘制非常困难。通过运用模糊函数的卷积算法，应用Matlab语言简便快捷地计算并绘制了三维模糊图、Fd切面图、Td切面图和模糊度图，并给出了绘制方法。

The frequency hopping coded signal is a new pulse compression radar signal, and has great analysis value. Ambiguity function is the main math tool for designing and analyzing the radar signal. It is very complicated to compute ambiguity function of frequency hopping ceded signal and difficult of draw the ambiguity figure. A method of computing the ambiguity function via convolution integral and drawing the dynamic three-dimensional ambiguity figure, Fd profile figure, Td section figure and ambiguity figure using Matlab language is presented in this paper.
