摘　　要：在雷达领域中,利用非线性调频脉冲压缩可提高脉压系统的性能.本文根据我们已建立的调频函数模型,提出了一种利用多参量遗传算法来产生满足脉压系统要求的非线性调频信号的方法,给出一个用该方法设计非线性调频信号的实例.实验结果表明,这一方法能够快速灵活地设计出所需信号.In the radar field,performance of pulse compression system can be improved through Non Linear Frequency Modulation (NLFM).On the basis of our model of frequency modulation function,a method,which can generate NLFM signal that mects the requirement of pulse compression system,is presented in this paper.An example of designing NLFM signal via the method is given.Computing result demonstrates that the method can design quickly and flexibly the desired signal.
