Space target scattering characteristic imaging in the visible range based on ray tracing algorithm

This paper simulated and calculated the visible light scattering of satellite target based on the material's bidirectional reflection distribution function (BRDF) and the reverse ray tracing algorithm, and on this basis, the target visible light imaging simulation is realized. The solar radiation in the visible range is calculated using the Modtran atmospheric transmission model. The ray tracing algorithm combined the geometric modeling of the target to realize occlusion and blanking judgment, and calculates the spatial distribution of target scattering intensity when visible light is incident.
