【摘要】：调研了ESA的"土壤湿度和海洋盐度"(SMOS)卫星和后续发展计划,以及NASA的"宝瓶座"(Aquarius)卫星;对比分析了SMOS和Aquarius卫星盐度测量数据的应用情况。结果表明:在低纬度地区,Aquarius卫星的盐度测量精度均优于SMOS卫星,但是在高纬度地区的盐度测量精度较差。针对2颗卫星在应用中存在的同步测量手段欠缺、射频干扰(RFI)等突出问题,提出了相应的解决途径,如增加同步测量和采用多种RFI检测抑制手段。最后,提出了海洋盐度探测卫星的发展趋势,如开展辐射计反演与遥感数据预处理技术、高精度外定标技术和高精度热控技术研究。
[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.
