摘要
介绍了目前多数雷达所采用的线性调频脉冲压缩信号的特点,分析了线性调频脉冲压缩信号旁瓣抑制的目的和方法,并引入加权窗函数,对其进行仿真,得出如何进行适当的加权处理,得到最佳的旁瓣抑制效果,达到雷达所需的技术性能。
This article introduces the characteristics of present linear frequency modulation(LFM)pulse compression signal used by most radars,analyzes the purpose and methods of LFM pulse compression signal sidelobe suppression,and introduces the weighted window function,carries on the simulation,educes how to make the appropriate weighting processing,get the best sidelobe suppression effect and achieve the technology performance needed by radars.
