摘　　要：针对传统线性调频信号匹配滤波的特点和仿真速度慢、效果不明显的问题，文中首先介绍了匹配滤波的概念以及传统线性调频信号匹配滤波的特点；然后结合圆周卷积重叠保留法对线性信号进行仿真，通过加权压缩得到了仿真结果。仿真结果表明，通过该算法可以得到需要的信号图像。The concept of matched filtering and the characteristic of traditional linear frequency modulation signals were introduced because of characteristic of traditional matched filtering of linear frequency modulation and also because the speed of simulation was too slow and the effect was unclear. After that the linear signals were simulated combining with circle convolution overlapping. The result of simulation was obtained after weighting compression. The result indicated that the wanted signal picture could be obtained.
