基于维纳滤波的船载地波雷达海流反演方法
A Current Inversion Method Based on Wiener Filtering for Shipborne Surface Wave Radar
摘要
Abstract
Ocean current is one of the crucial parameters in many fields such as physical oceanography,marine environmental pro-tection,and marine resource development.Compared to shore-based radar,shipborne radar has better flexibility and maneuver-ability,and can be used for detecting ocean surface information in areas far from the coastline.However,in the process of ocean exploration,due to the influence of sea winds and waves,it is difficult for shipborne platform to maintain a stable heading,and the radar wave scattering echo characteristics change.In order to extract ocean current parameters more accurately,it is necessary to compensate for the platform's yaw motion during the ocean current inversion process.Based on the antenna array signal model and shipborne platform motion model,the time and frequency domain expression of the echo signal under the influence of platform yaw motion is derived in this paper,and a deconvolution method based on Wiener filtering for motion compensation is proposed.In addi-tion,the proposed method is validated using both simulation and experiment of shipborne high frequency radar,and the results show that the radial current estimation error is decreased by 4.18 cm/s after yaw motion compensation,which shows the effectiveness of the proposed current inversion method.关键词
