摘要
基于相控阵雷达的工作原理和各种工作方式下的性能特点、结合天气雷达的基本要求、并考虑到相控阵雷达在生产、应用技术方面不断地成熟、成本的飞速地下降和财政的宽裕,展望有源数字相控阵多普勒天气雷达的选用。介绍有源数字相控阵多普勒雷达发展现状和作为天气雷达所面临的问题:如减少数字T/R组件的总成本、各种数字波束形成模式及自适应技术的移植和改进、数据信号处理(软硬件)技术和气象产品的开发、耗电计算,以及全寿命期间的设备保障等,提出解决部分问题的初步设想。
Based on the working principles and performances under each working models of phased array radar,combined with the basic demands of weather radar,taking account of continual technology development,fast cost reduction,and increasing financial investment in phased array radar in China,the application potentials of active digital phased array Doppler weather radar are expected.The current development status of active digital phased array Doppler radar and challenges facing weather radar are introduced,such as the reduction of the total costs of the radar＇s digital T/R components,the transplantation and improvement of each kinds of digital beam forming models and self-adaptation technologies,the development of the digital signal process（software and hardware）technologies and weather products,power consume,the technical support of equipment during the total life cycle of radar,and so on.The preliminary ideas to solve some problems are put forward.
