Analysis on detection capability of two-generation space-based infrared sensors on the tail-flame of stealth aircraft
摘要
Abstract
In order to compare the detection capability of the two-generation space-based infrared sensors on the tail flame of stealth aircraft,the American SBIRS-GEO and Next-Gen OPIR constellations are taken as the research objects,and by establishing the high-orbit infrared detection model and constructing the corresponding early-warning detection scenes,quantitative comparison is made on the radiance response of the two-generation sensors to the air-craft tail-flame of different flight states,as well as the simulation imaging effect.The results of research are shown as follows:The two-generation space-based infrared sensors can be used to detect aircraft tail-flame signals.Aircraft af-terburner has a significant effect on the temperature and shape of the tail-flame,which is a key factor affecting the de-tection performance of space-based infrared sensors.The new-generation sensors carried by Next-Gen OPIR can cap-ture and detect the tail-flame in a non-afterburner state at an altitude of 36,000 km,and their imaging signal-to-noise ratio is significantly higher than that of the SBIRS-GEO sensors for the tail-flame in the afterburner state.The ob-servation angle of satellite also has a non-negligible influence on the detection performance of aircraft tail-flame.关键词
