摘要
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。模糊函数是对雷达信号进行分析研究和波形设计的有效工具 ,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。本文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具有良好立体效果的三维模糊图 ,制作了Fd 切面图、Td 切面图和模糊度图 。
The frequency hop code pulse signal is a new form of pulse compression radar signal, and is of great analysis value. Ambiguity function is a useful tool for designing waveform and analyzing the radar signal. It is complicated to compute ambiguity function of frequency hop code signal and difficult to draw the ambiguity figure. This paper presents a method of computing the ambiguity function via convolution integral and drawing the ambiguity figure by using the Matlab language .
