Abstract


In this paper, the target laser and visible spectral scattering characteristics , combined with a the STK software system numerical simulation of the scattering characteristics of the visible spectrum of the goals of the movement space . Based on a rough surface electromagnetic scattering theory , bidirectional reflectance distribution function of angle from the visible spectrum , the reflectance spectrum of satellite covering materials and solar panels , the calculation of space target scattering intensity of the visible spectrum measurement and analysis , discuss the value of satellite surface BRDF incident wavelength , the influence of the material properties of the surface . Measured the material space the target model material surface spectral BRDF, numerical calculation simple goals and portfolio objectives laser and visible spectral scattering intensity spatial distribution of different covering materials on the visible spectrum of scattering intensity and laser light scattering intensity angle distribution . The paper describes the large - scale simulation software STK system , based scene generation technologies , describes the implementation process of data visualization . The coordinate system transformation matrix formula derived space goals , and the Euler angles and quaternion transformation matrix , which can STK software space moving target orbit and attitude data conversion into application data . Embed target light scattering Software module in the STK system to calculate different observation point estimates to the target space motion scattering intensity of the visible spectrum , and analysis of the impact of the light scattering intensity of different covering materials for space moving target , initially based STK space moving target platform demonstration and simulation of light scattering characteristics .
