摘要
在对线性调频信号及脉冲压缩的原理进行简单的介绍后,给出雷达成像R-D算法中方位脉冲压缩实现的具体方法,设计方位脉冲压缩的模块化结构,然后在FPGA进行实现。文中指出了基于FPGA的系统中各个模块的作用以及具体的实现方法,给出仿真结果并进行总结。
The principle of chirp signal and pulse compression is briefly introduced, and an implementation of direction＇pulse compression using in radar image R-D algorithm is given. The modular structure of the direction pulse compression is designed and then realized on FPGA. The role of each module of the FPGA- based system and their respective realization are presented. Finally the simulation result is given.
