Ocean Surface Wind Speed Retrieval Using Spaceborne GNSS-R

  • 摘要: 星載GNSS-R因其時(shí)延-多普勒相關(guān)功率(DDM)波形對(duì)風(fēng)速的敏感性較低,采用理論與實(shí)測(cè)波形匹配的方法所得風(fēng)速精度較差。針對(duì)這一問題,該文采用一種直接建立相關(guān)功率值與風(fēng)速之間聯(lián)系的方法獲取風(fēng)速信息。基于相關(guān)功率模型對(duì)散射功率進(jìn)行了歸一化修正及其簡(jiǎn)化處理,利用UK TDS-1衛(wèi)星試驗(yàn)數(shù)據(jù)和散射計(jì)(ASCAT)同比觀測(cè)風(fēng)速分別建立歸一化散射功率及其簡(jiǎn)化式與海面風(fēng)速之間的經(jīng)驗(yàn)?zāi)P?。與ASCAT觀測(cè)風(fēng)速對(duì)比結(jié)果表明:在0~20 m/s的風(fēng)速范圍內(nèi),采用歸一化散射功率反演風(fēng)速的均方根誤差為2.11 m/s;兩種方法的反演精度相近,簡(jiǎn)化修正方式避免了復(fù)雜的積分運(yùn)算更適用于實(shí)時(shí)處理。
