Paper Abstract

Multi-band IR data of the space object can be used in the fields of object identification and space surveillance. The radiation characteristics of the object can be obtained by analyzing these data. These characteristics include temperature, area, emissivity, absorptivity, reflectivity, and temporal trends. The infrared radiation temperature of the space object is an important characteristic from which the object's working state in orbit can be judged. We apply the method of measuring the spectral distribution of the object and fit the data to the Planck formula to determine the temperature. In order to improve the precision of measuring temperature on the space object, we optimize the centric wavelength and the bandwidth effectively. Also, we use a simple program to implement temperature measurement.
