摘　　要：提出了在地球静止轨道上利用高分辨率固态成像器件按“凝视”模式观测地球的设想，分析了按凝视模式工作时的各种几何关系，并根据目前和近期能达到的固态成像器件的水平，以５０００２像元的ＣＣＤ器件和１０００２像元的红外焦平面阵列作为探测器，提出了性能分别类似于ＶＨＲＲ和ＧＯＥＳ－９成像仪的两种传感器的设计方案，并与之比较。分析结果表明，在静止轨道上按“凝视”模式观测地球是在气象观测和海洋遥感中很有吸引力的方案。This paper describes a project that the earth can be observed in the staring mode with the high resolution solid state imaging device in the geostationary orbit,analyzes the geometric relations when the sensor operates in the staring mode,and according to the current solid state imaging devices,gives two kind of sensor designs employing 5 000 by 5 000 elements CCD and 1 000 by 1 000 elements infrared FPA,similar to VHRR and GOES 9 in performance.The analysis results indicate that it is a very attractive project in the meteorological and ocean remote sensing to observe the earth in the staring mode in the geostationary orbit.
