基于RFSoC的脉冲雷达采集与测量系统设计与实现
Design and implementation of a pulse radar acquisition and measurement system based on RFSoC
摘要
Abstract
To investigate the application of RF system level chip—Radio Frequency System-on-Chip(RFSoC)in pulse radar system,a radar ranging system with high performance digital-analog hybrid signal processing capability is designed.The high-performance RFSoC development board—IW-RFSoC-49DR(including the design of the background interference filtering algorithm)is adopted,and the test environment is set in a laboratory with narrow space and disturbed multimetallic equipments.The results of the experiments show that the experimental data are significantly disturbed in an untreated,complex indoor environment;after implementing the background interference filtering algorithm,the display resolution of the frequency spectrum map has been significantly improved.As the test target distance increases from 3 m to 12 m,the ranging error decreases from 53 cm to 5 cm.RFSoC technology shows significant advantages in the design of pulsed radar system,realizing the high integration and low power consumption design,and laying a foundation for the subsequent design of portable radar based on RFSoC.关键词
