双基地多普勒雷达的风场反演能力评估

摘要

主、被动相结合的双基地天气雷达风场反演技术，是国际上近年来发展的新型技术。为了评估该技术的风场反演能力，将X波段双基地雷达（主、从站）联合反演的风场，与X/S波段多普勒雷达（双主动雷达）联合反演的风场进行对比。结果表明，在降水天气过程中，两者反演的风场一致性较好。此外，对方法中存在的问题也做了一些讨论。%Wind ifeld retrieval by bistatic Doppler radar is a new type of technology, which has been developed in China recently. To assess the ability of this technology, in this paper, two wind ifeld retrieval methods derived from bistatic X-band radar and X/S band Doppler radar are compared. The analysis results show that the two wind ifeld retrieval methods are reasonably consistent. In addition, some problems of the bistatic technology are also discussed.
