Design and Implementation of a Multichannel Pulse Compression System Based on FPGA

摘要

—The implementation of digital signal process system based on FPGA is an important method for embedded system. Pulse compression can be implemented in digital method. The realization of a multichannel pulse compression system by using all digital method has the characteristics of high reliability, strong anti-disturbance, good flexibility and convenient for application. In essence, pulse compress is a method of frequency spectrum expanding, and is used in matched filtering. It incarnates the matching level of filter and the expectant phase of received signal. A multichannel pulse compression system is designed using FFT IP core which can be reused in different periods of digital pulse compression, respectively performing FFT and IFFT calculation, so that the hardware consumption is saved significantly. This paper presents the logic programming of Multichannel Pulse Compression System based on Xilinx FPGA, and introduces the highspeed transmission module, the digital signal process module and the data buffer module in detail.
