Keyword神舟4号飞船 多频段微波辐射计 穿透 浅表层遥感 塔克拉玛干沙漠
Abstract利用神舟4号飞船多频段微波辐射计结合其它星载数据和地面数据,研究了塔克拉玛干沙漠的微波辐射特点和温度反演问题.结果表明,微波辐射计在塔克拉玛干沙漠的性能是相对稳定的.其在塔克拉玛干沙漠的观测亮温呈现出低频高于高频的特点.通过分析.认为这种现象与微波辐射的穿透能力密不可分.通过对各通道观测亮温与沙漠周围5个常规气象观测站的温度资料的相关分析,表明观测亮温与地表要素间有很好的相关性.
Other AbstractM icrow ave em ission and temperatu re ret rieval p rob lem s have been studied with data of ShenZhou2IV Spacebo rneM u lt ip le BandM icrow ave Radiometer.The data standard deviat ion of eacht rack is about 2.5 K, w h ich is in the same level of SMMR above the same site.The study shows that the Radiometer has been operat ing stab ly. The b righ tness temperatu re ob served in low 2f requency channels is higher than that in high-frequency channels.This phenomenon is clo sely related to m icrow ave samp ling dep th w hen it is compared w ith other data such as meteorological observation and optical remotesensing data. The ob served b righ tness temperatu re has good co rrelat ion w ith su rface parameters by co rrelation analysis betw een ob served brigh tness temperatu re of each channel and su rface temperatu re.
