Design and test of signal processing hardware for two-dimensional phased array digital multi-beam system

Abstract

With the increasing use of digital array radars, radar signal processing systems have higher performance requirements. This article introduces a signal processing hardware design for the two-dimensional phased array digital multi-beam system. Because of its digital multi-beam characteristics, it is very demanding on the radar signal processing system's computing power, processing speed, and data throughput. This paper proposes a design of signal processing hardware based on Xilinx FPGA Virtex-7 and two multi-core digital signal processors (DSP) to meet the requirements of two-dimensional phased array digital multi-beam system. Subsequent experiments and engineering practices show that this design scheme can fully meet the requirements of the system.
