The Research On Distribute Simulation Of APT On Laser Communication Between Plane And Satellite

In this paper, we analyzed the power spectral density of optical communication platform and found that the power of vibrancy was mainly concentrated at several peaks. So we use the method of filter designed according to power spectral density to produce the vibrancy data of optical communication platform. On the basis of the quantum theory, the optical energy and various noise of CCD could be converted to equivalent electric charges, and then the facular detection model of CCD was proposed. The atmosphere turbulence was seen as weak fluctuation turbulence, and Gaussian noise was used to simulate influence of atmosphere turbulence on transmission of laser beam. The I/O relation and characteristics of tracking subsystem of APT were simplified, and then its model was established. The arithmetic of the above models was also proposed in this paper. A distributed simulation system of APT which based on HLA was proposed in order to realize distributed collaborative simulation. A method of hardware in loop evaluation on the credibility of simulation system was proposed.
