Paper Abstract

In the satellite remote sensing the resolution of the satellite image is always a restriction on the obtaining information and it is impossible that the resolution of pixel is unlimitedly raised. In the infrared region, the pixel values in a uniform picture element isn't effected by the resolution of pixel, but it is another case to some non- uniform picture elements. Each pixel value corresponds to the integration by the radiant excitance of the earth's surface inside of the pixel and is associated with not only the area of same radiation temperature but also the value of radiation temperature inside of the element. In this paper, the relationship between the pixel values and the area of same radiation temperature as well as the value of radiation temperature inside of the pixel was presented. A new train of ideas was given for the obtaining more information by today's resolution of pixel. With the help of this result, the monitor of some natural calamities (for example, the forest fire, the flood, the plant diseases and insect pests, etc.) will become much timely and they could be controlled as soon as possible.
