Research of Infrared Electro Optical System’s Operating Range on Hypersonic Vehicle

Abstract:

The operating range of ground-based detector on hypersonic vehicle in rarefied atmosphere space is researched. Both the imaging dispersion and the difference of radiation intensity between object and background are considered, and a new model of operating range is proposed. By experiments, the dispersion coefficient changes with the distance between object and detector and has great effect on operating range; meanwhile, the higher the velocity of vehicle is, the further the operating range is. And the detector working at medium wave infrared has larger operating range. Compared with existing method, the proposed algorithm achieves better result in the field experiment.
