摘　　要：针对高频地波雷达浅海观测尝试中面临的参数反演新问题进行了研究.描述了高频地波雷达浅海探测机理,提出了多站高频地波雷达海洋参数反演方法,并推导了利用多站高频地波雷达回波多普勒谱反演浅海水深和矢量流的理论模型.通过三站探测和多站探测的反演数值模拟,表明了多站浅海探测的可行性和反演方法的有效性;通过分析苏北浅滩的三站高频地波雷达观测试验数据,表明了本文反演方法的实用性,这对于利用高频地波雷达进行浅海海洋环境探测的实际工程应用具有广阔的前景.In order to extract the ocean dynamic parameters from shallow water, water depth, and current inversion at multiple （three or more） sites, HFSWR （high frequency surface wave radar） sea echo is developed. In this paper the inversion principle and theoretical model are presented in detail, and the proposed idea is verified for three or more than three sites, which shows prospects in practice. By analyzing the data collected from three HFSWR detection experiments in northern Jiangsu province, the inversion results show good performance, which is promising for extracting ocean water depth in inner zone and shallow water by HFSWR in engineering application.
