Analysis on the Effective Ranging of TV Tracking for Low Altitude Target
The influence on the TV tracking effective ranging in regard to both the signal and the forget-to-background contrast is analysed on the features of long-distance tracking and measuring of the target travelling at low altitude, based on the experience in development of opto-electronic tracking and measuring instrument. The discussion is emphasized on the dynamic contrast formed as the target passing across the TV field of view and its influence to the effective ranging. A method is proposed to improve the dynamic target-to-background contrast and to expand the TV tracking effective ranging by adopting electronic shutter and spectral matching techniques.
