【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(jì)劃,以及NASA的"寶瓶座"(Aquarius)衛(wèi)星;對(duì)比分析了SMOS和Aquarius衛(wèi)星鹽度測(cè)量數(shù)據(jù)的應(yīng)用情況。結(jié)果表明:在低緯度地區(qū),Aquarius衛(wèi)星的鹽度測(cè)量精度均優(yōu)于SMOS衛(wèi)星,但是在高緯度地區(qū)的鹽度測(cè)量精度較差。針對(duì)2顆衛(wèi)星在應(yīng)用中存在的同步測(cè)量手段欠缺、射頻干擾(RFI)等突出問題,提出了相應(yīng)的解決途徑,如增加同步測(cè)量和采用多種RFI檢測(cè)抑制手段。最后,提出了海洋鹽度探測(cè)衛(wèi)星的發(fā)展趨勢(shì),如開展輻射計(jì)反演與遙感數(shù)據(jù)預(yù)處理技術(shù)、高精度外定標(biāo)技術(shù)和高精度熱控技術(shù)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.
