| 摘 要： | 文章研究了在相位逗留原理的基础上采用由多种窗函数线性组合得到的组合窗设计NLFM信号的波形与脉冲压缩滤波器，重点分析了组合窗函数的组合参数及窗函数数量对NLFM信号脉冲压缩结果的影响。仿真结果表明，在一定条件下对基于三种窗函数线性组合的组合窗设计的NLFM信号进行谱修正滤波后，主副瓣比（RMS）可提高4．6～8．9dB，而主瓣展宽和主瓣损失变化较小。

| Abstract: | The technique combination window function is applied in the design of NLFM signal and pulse compression filter is studied in this paper.The influence of the coefficients and the window numbers for the combination window function on the performance of the pulse compression are analyzed.The simulation results under given conditions demonstrate that when the design of the NLFM signal and modified spectrum filter is based on the combination window function linear combined by three window functions,the Ratio of ... |
