RESEARCH ON SPACE TARGET DETECTION ABILITY CALCULATION METHOD AND SPECTRAL FILTERING TECHNOLOGY IN SKY-SCREEN'S PHOTOELECTRIC SYSTEM

摘要

Sky-screen is a photoelectric sensor to detection flying target information in shooting range, to improve the detection ability of sky-screen in strong background luminance, this article establishes the sky background luminance calculation model and the detection ability calculation model of sky-screen, researches the space targets characteristics and SNR (signal-to-noise ratio) calculation model, analyzes the influence factors of strong background luminance and study different spectral filtering methods to improve the detection performance, discusses the influence factor that sky background luminance change and different layouts of sky-screen to the detection system of sky-screen. Through the calculation and experiment analysis, the results of the theoretical calculation and experiment testing on the detection ability of calculation model of sky-screen are consistent, and the spectral filtering technology can improve the signal-to-noise ratio and the space target detection ability effectively in sky-screen.
