Abstract

Abstract: Based on the Variations Seculaires des Orbites Planetaires (VSOP) 87 theory, an approach for generating infrared radiant scene of planetary background was presented. With the VSOP87 theory, the heliocentric coordinates of eight planets in the solar system were worked out at given time. The coordinates were revised by time correction so that real coordinates were achieved. The corrected heliocentric ecliptic coordinates of planets were converted into geocentric horizontal coordinates according to the position of the observer. After that, the projected coordinates and projected radiuses of planets were achieved from projection transformation based on the field of view (FOV) and line of sight, then which planet appeared in the FOV was realized. In accordance with the radiant calculation, the irradiance at the sensor of planets was computed, and the infrared radiant image of planets in given FOV was generated. With these steps, a model which can simulate the infrared radiation of planets in the given FOV at any given condition was achieved.
