基于FPGA的分段复用脉冲压缩实现方法

Realization Method of Multiplexing Pulse Compression Based on FPGA

脉冲压缩是脉冲雷达常用的处理方式,以现场可编程门阵列(FPGA)为硬件平台的脉冲压缩设计需要考虑资源消耗和设计的灵活性。利用重叠保留法和快速傅里叶变换(FFT)算法,在频域实现了分段复用脉冲压缩,有效地节约了硬件资源,通过设置分段参数和匹配系数,可适用于多种时宽调频信号的信号处理系统。

Pulse compression is usually used in pulse radar.The resource consumption and flexibility of the design need to be considered when pulse compression based on field programmable gate array (FPGA) is achieved.This paper uses overlapping reservation algorithm and fast Fourier transform (FFT) algorithm to achieve multiplexing pulse compression in the frequency domain,and effectively save the hardware resource.The design may be utilized in the signal processing system for various time-width frequency modulation (FM) signals by setting up fragment parameter and matching coefficient.
