摘要
首先介绍了非线性调频（ＮＬＦＭ）脉压波形设计的一般原理，在此基础上提出了一种优化设计方法。用该方法设计的ＮＬＦＭ波形距离副瓣更低，且能得到调频函数和调相函数关于时间ｔ的显函数形式。最后分析了模拟目标回波经脉压滤波器的处理结果。
The general theory of designing nonlinear frequency-modulated(NLFM)signals is described at first and an optimization method based on the theory is proposed,It shows that the NLFM signals designed by the improved method are capable of providing lower range-sidelobes,also the frequency and phase modu- lotion function can be derived in the apparent form of time. Finally, the results of the simulated target echo signals passing through a compressed filter are analyzed.
