相控阵天气雷达与多普勒雷达回波的对比分析

Comparison of Echo between Phased Array Radar and Doppler Radar

介绍相控阵天气雷达研究进展及其技术特点,并利用相控阵天气雷达和抛物面天线雷达的观测数据进行了对比分析。结果表明,相控阵天气雷达比普通雷达具有更灵活快捷的扫描能力,强度回波的分布和数值比较接近,但相控阵雷达的强回波区略强,回波细节更丰富,是探测中小尺度灾害天气系统的更理想工具。

The research process and technical features of phased array radar is introduced and a comparative analysis is conducted between the phased array radar and parabolic antenna radar.Results show that,compared with common radars,phased array radar has faster and more flexible scanning capacity,although they share similar distribution and values of echo intensity,the phased array radar has slightly stronger strong echo region and richer echo details,so it is the ideal tool to measure the meso-and micro-scale weather system.
