For pre-launch field radiometric calibration for the visible channel of scanning radiometer of satellite FY-2-05,the traditional radiation calibration method has been adopted,on the other hand,a novel method called Detector Based Reflectance Calibration(DBRC) which is independent of spectral response function of scanning radiometer has been advanced.
为了对FY-2号05星扫描辐射计可见光通道进行发射前外场辐射定标,在采用了传统的辐亮度定标方法的同时,提出了一种新型的独立于扫描辐射计可见光通道光谱响应函数的基于标准探测器的反射比定标法(Detector Based Reflectance Calibration)。
In this paper the logical structure of contactless telemechanical system for distributed objects is discussed. A simple method of variable system structure for transmitting and receiving telemechanical information is adopted. The idea is that the information oc-curred in every controlled point (station) and the information of some of those objects,which frequently change their states, are transmitted continually and cyclically, while for other objects their information is transmitted only after any change i...
Strain-gage indicator is one of the electrinical instruments for measuring non-electrical quantities. This kind of instrument may be used to measure the quantity of strain in engineening structural members. For this purpose, it is necessary to transform the non-elee-trical quantities(Strain)by the pick up (Strain gage wire)into quantities of the variation of electrical resistance. The sensetivenessan anb precision of the quantities of strain which is measured by the strain gage indicator is much higher then...
