摘要
为解决雷达作用距离和距离分辨力的问题,分析了线性调频脉冲压缩的原理及工程实现方法,并利用Matlab软件对加权前后的线性调频信号脉冲压缩波形进行对比。简述了分布式(DA)算法的基本原理,给出一种基于FPGA分布式算法的时域脉冲压缩实现结构,利用QuartusⅡ软件完成脉冲压缩处理模块设计以及波形仿真。通过分析可以得出基于分布式算法实现的脉冲压缩可以减少资源利用率,大大节省硬件资源。
In order to solve the problem between operating distance and range resolution of radar, the principle of LFM pulse compression and the method of engineering realization are analyzed, and the pulse compression waveforms of linear FM signals before and after weighting are contrasted with Matlab software. The basic principle of DA （distributed arithmetic） is described briefly. A structure of time domain pulse compression based on FPGA DA is given. The module design and wave- form simulation of pulse compression is achieved with QuartusⅡ softwave. The analysis indicates that the pulse compression obatained on the basis of DA can improve the resource utilization and save hardware resources significantly.
