FPGA realization of signal processing for two-dimensional phased array digital multi-beam radar

Abstract

With the increasing use of digital array radars, radar signal processing systems are faced with the challenge of real time processing for a mass of data. A kind of field programmable gate array (FPGA) realization of signal processing is proposed for two-dimensional phased array digital multi-beam radar in this paper. This scheme can realize the real-time signal processing of 6 beams at the same time. Each beam processes data from 8400 range gates. The details of implementation including digital multi-beamforming (DBF), pulse compression and moving target detection (MTD) are described. The results show that the design is correct and feasible.
