利用相控阵雷达实现气象探测

Realization of Meteorological Observation Using Phased Array Radar

短时临近气象预报需要天气雷达对天气目标进行定量测量,以便对天气现状以及发展趋势做出准确预判。相控阵雷达应用于气象探测,利用其多通道以及快速多变的波束扫描能力实现对天气目标的快速扫描,雷达系统设计采用实时在线标校的技术设计,能提高探测的可信度和气象产品的质量。文中在分析了气象探测原理的基础上,给出了微波相控阵雷达实现对气象目标定量探测的设计思路与技术要点。

Nowcast need weather radar to measure weather targets quantitative, so as to the current situation and development trend to make accurate predictions. Phased array radar uses the multi-channel and fast changing beam scanning ability to realize the tar- get of the quick scan. Radar system design can improve the detection of credibility and weather the quality of the products by using real time on-line calibration technology. It is pointed out that microwave phased array radar could realize the quantitative detection of meteorological target design and technical points on the basis of principle of meteorological observation.
