摘要

In this paper, the authors discuss the detection limits of systems for detectingnonluminous artificial satellites in daylight, as well as the relationship of target contrast and signal-to-noise ratio to artificial satellite characteristics, sky background characteristics, optical system parameters, and CCD (charge-coupled device) parameters. The authors discuss in depth the effects of spectral filtering technology on detection limits, contrast, and signal-to-noise ratio. Results of numerical simulations demonstrate that spectral filtering technology can increase the target satellite's optical contrast by 4 to 8 times, raise the target satellite's signal-to-noise ratio by 1.3 to 2.3 times, and enhance the system's limit detection brightness by 0.4 to 0.7 visual magnitude.
