The system comprises a fixed star database reading module, a satellite dynamics simulation database, a satellite initial parameter configuration module, observation satellite dynamics simulation and control, target satellite dynamics simulation and control, observation satellite load rotary table simulation, a target visibility determination module, observation satellite load imaging simulation and an observation result simulation output module. According to the invention, with whole space-based observation physical process simulation as a starting point, a space-based observation process including various models of the observation satellites, observation load, the target satellites, the fixed star, etc. is established and simulated, and space-based observation simulation results with high confidence are output.

Description

technical field [0001] The present invention relates to computer simulation techniques for space-based observations. To be precise, it is a space-based observation simulation system and method for satellite targets and stellar targets. Background technique [0002] In order to use space more effectively and explore space more deeply, all space powers are actively researching space surveillance technology. Space surveillance is mainly to detect, identify and track specific space targets, mainly through ground-based observation systems and space-based observation systems. Compared with the ground-based observation system, the space-based observation system has the following significant advantages: it is not restricted by geographical location and meteorological conditions, and can observe targets from different azimuths; Higher signal-to-noise ratio; the space-based observation system is in orbit, and only one star is needed to cover the entire geosynchronous orbit. In view...
