Extracting scattering characteristic from photoelectric/IR reconnaissance satellites targets

Satellites targets scattering characteristics is the basis of the monitoring, identification and striking for the military objectives, the scattering characteristic controlling is also the important part of system design for satellites. Firstly, the boundary conditions of photoelectric reconnaissance satellites configuration was determined, based on the threat of satellites facing and the load characteristics of satellites loading, the composition and character of the complicated satellites' scattering construction were analyzed. The scattering characteristic of typical satellites target was simulated by SBR method, PO method and EEC method on different frequency and angle. The Defense Support Program was taken as an example to build the structure mesh model, electromagnetic simulation model. Based on the scattering simulation conclusion of DSP model for frequency, polarity and incidence angle, the scattering characteristic of photoelectric/IR reconnaissance satellites targets was extracted. The scattering highlights and stealth improvement suggestions were given, which could be used to guide the target detection and stealth design for satellites targets.
