线性调频信号是现代雷达系统中一种常用的信号形式，通过脉冲压缩处理,可以得到良好的距离和径向分辨率。在研究线性调频信号脉冲压缩基本原理的基础上，得出通过时域匹配滤波、基本运算卷积加法等处理实现信号脉冲压缩的方法，并做了MATLAB仿真分析。详细介绍了基于FPGA技术的线性调频信号脉冲压缩的设计方法,使用Xilinx公司的XC6VLX240T芯片和ISE开发软件进行硬件系统的实现，并将结果与仿真效果进行比对，验证了硬件实现脉冲压缩的可行性与有效性。
Linear frequency modulation signal is a kind of commonly signal form used in modern radar system, through the pulse compression process, high distance and velocity resolution can be obtained. On the research of he basic principle of pulse compression of LFM signal, obtained a method to realize signal pulse compression processing by using the time matchfilter and convolution operation, and ananalysis simulatied in MATLAB is given here.Introduces in detail the pulse compression of LFM signal based on FPGA technology, Xilinx company XC6VLX240T chips and develop software ISE is used to realize the hardware system, and to compare the results with the simulation results, demonstrates the reliability and feasibility of realizing pulse compression by hardware.
