Abstract: Modern war requires that the battlefield target search equipment can quickly and automatically search, discover and identify the long-distance targets under the condition of mobility, and sorts the threat of enemy targets, then accurately locates the coordinates of the targets, and transmits the target information to the rear. A new type of sighting system for armor vehicles was proposed. The five modules of the system, panoramic module, visible continuous zoom module, high-performance infrared thermal imager module, intelligent control module and pan tilt zoom (PTZ) optical mechanical module were studied and designed. In addition, the composition, principles and key technologies of the system were discussed. The results of functional test and precision test after prototype development show that the integrated sighting system has correct principle, high reliability, stable accuracy as high as 0.06 mil (1σ), and strong rapid response ability, which provides a cost-effective way to realize the anti-terrorism of armor vehicles.
