Abstract

With the rapid development of intelligent driving and unmanned systems, environmental perception imposes higher requirements on the accuracy and real-time performance of radar sensors. This paper presents an efficient millimeter-wave radar target detection system based on an FPGA-based hardware-software co-design approach. The system uses the PZ7020 as the core processing unit, combined with LD2450 and LD2451 millimeter-wave radars, and achieves high-speed multi-target information transmission via UART, and performs data acquisition, buffering, filtering, and parsing on the FPGA. On the software side, a data frame parsing program based on interrupt and buffer mechanisms is designed to ensure the completeness and real-time performance of data reception. Experimental results show that the system can stably output target distance, velocity, and angle information, with an accuracy exceeding 86% and error ranges within acceptable limits for engineering applications, demonstrating the feasibility and practicality of the proposed solution.
