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,而本文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.
脈遲壓縮體製雷達的髮射信號通常包括多種線性調頻信號,這就要求對迴波信號的脈遲壓縮處理適應性要彊,如果採用定點脈壓,不同信譟比的迴波信號脈遲壓縮結果的截位各不相同,需要分彆進行倣真測試,以確定截位的位置,而本文提齣一種浮點頻域脈壓的算法及實現,基于Xilinx FPGA IP覈,無需攷慮截位,對各種信號適應性彊,方便易用.

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 in this paper,a floating-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.
