低空监视雷达气象信号处理的设计与实现

摘要

随着低空空域管理改革的不断深化，在机场附近装备具有目标监视和气象探测多种功能的雷达具有重要意义。通过对多普勒气象雷达信号处理技术的研究，解决了低空监视雷达中实现气象信号处理功能所面临的一系列问题，并给出了系统设计方案及其软硬件实现过程。试验结果表明，该信号处理系统具有结构简单、实时处理能力强和可靠性高等特点，初步实现了在低空监视雷达中目标探测与气象探测的兼容。%With the deepening of the reform on low altitude airspace management,the equipment of target surveillance and meteor-ological detection multifunction radar around airport is of important significance.According to the research on Doppler weather radar sig-nal processing technology,this paper finds out a serial of problems of weather signal processing at low altitude surveillance radar system, and proposes the system design schemes and the implementation processes of software and hardware separately.The experimental results show this signal processing system has such characteristics as simple structure,high realtime processing capability,high reliability,etc., and realizes the compatibility of target detection and weather detection at low altitude surveillance radar system.
