【摘要】：調(diào)研了ESA的"土壤濕度和海洋鹽度"(SMOS)衛(wèi)星和后續(xù)發(fā)展計劃,以及NASA的"寶瓶座"(Aquarius)衛(wèi)星;對比分析了SMOS和Aquarius衛(wèi)星鹽度測量數(shù)據(jù)的應用情況。結果表明:在低緯度地區(qū),Aquarius衛(wèi)星的鹽度測量精度均優(yōu)于SMOS衛(wèi)星,但是在高緯度地區(qū)的鹽度測量精度較差。針對2顆衛(wèi)星在應用中存在的同步測量手段欠缺、射頻干擾(RFI)等突出問題,提出了相應的解決途徑,如增加同步測量和采用多種RFI檢測抑制手段。最后,提出了海洋鹽度探測衛(wèi)星的發(fā)展趨勢,如開展輻射計反演與遙感數(shù)據(jù)預處理技術、高精度外定標技術和高精度熱控技術研究。
[Abstract]:The (SMOS) satellite of ESA "soil moisture and marine salinity" and its follow-up development plan, and the "Aquarius" (Aquarius) satellite of NASA are investigated, and the application of the salinity measurement data of SMOS and Aquarius satellites is compared and analyzed. The results show that the salinity measurement accuracy of Aquarius satellite is better than that of SMOS satellite in low latitude region, but the salinity measurement accuracy in high latitude region is poor. In view of the shortage of synchronous measurement means and the outstanding problems of RF interference (RFI) in the application of two satellites, the corresponding solutions, such as increasing synchronous measurement and adopting various RFI detection and suppression methods, are put forward. Finally, the development trend of marine salinity detection satellite is proposed, such as radiometer inversion and remote sensing data preprocessing technology, high-precision external calibration technology and high-precision thermal control technology.
