New control technology for visible light reflection characteristics of space target

Abstract

For geosynchronous( GEO) orbit space object's detection and recognition is mainly dependent on analysis,identification and judgment of reflected sunlight photometric curve. Based on analysis of visible light reflection characteristics calculation model of space target surface diffuse reflection properties,a study on different shape reflector light reflection characteristics was carried out. Moreover,a different shape reflector method was proposed to control space target light reflection characteristics. Taking an example of a GEO satellite,simulate and analyze the effects of cone,sphere and cylinder as reflection control body on satellite reflection characteristics by using Monte Carlo non-sequential light tracing method. The results show that the method can change the satellite original visible light reflection curve,reduce the probability of being detected and recognized,and improve the invisibility of space object.
