基于Xilinx FPGA IP核的浮点频域脉冲压缩算法的设计与实现

摘要

Pulse compression radar transmitting signal usually includes a variety of linear FM signal, which requires the echo pulse compression processing adaptability stronger, if the point pulse pressure and different signal to noise ratio of the echo signal pulse compression results truncate each are not identical, necessary to simulation test, to determine the truncation of the position, and the A lfoating-point pulse compression in frequency domain algorithm and implementation, based on Xilinx FPGA IP core, without considering the truncation and adaptability to various signal is strong, easy to use.%脉冲压缩体制雷达的发射信号通常包括多种线性调频信号,这就要求对回波信号的脉冲压缩处理适应性要强,如果采用定点脉压,不同信噪比的回波信号脉冲压缩结果的截位各不相同,需要分别进行仿真测试,以确定截位的位置,而文章提出一种浮点频域脉压的算法及实现,基于Xilinx FPGA IP核,无需考虑截位,对各种信号适应性强,方便易用.
