摘　　要：探讨射频系统级芯片(RFSoC)在脉冲雷达系统设计中的应用,设计实现一个具有高性能数模混合信号处理能力的雷达测距系统。采用IW-RFSoC-49DR高性能RFSoC开发板(包括背景干扰滤除算法的设计),测试环境设置在空间狭窄、多金属设备干扰的实验室内。实验结果显示,在未经处理的复杂室内环境中,实验数据受到显著干扰;实现背景干扰滤除算法后,频谱图的显示分辨能力得到显著提升。随着测试目标距离由3 m提高至12 m,测距误差值从53 cm降低至5 cm。RFSoC技术在脉冲雷达系统设计中展现出显著优势,实现了高集成度低功耗设计,为后续基于RFSoC设计便携式雷达打下了基础。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.
