Abstract
Laser target designator device two main function is to provide target the weapons search and ranging. In this paper, "Optical Receiver Test System" and "laser target instruction device optical axis correction device" research project as background, the following studies. (1) according to the system application background and discusses the semi-active laser guidance technology on anizational structure and basic operation. (2) the role of laser-guided accuracy and distance are analyzed. (3) the performance of optical receivers on the guidance precision and measurement range have a major impact.(4) to determine the optical receiver testing methods and testing standards, using-the-loop simulation method designed a dedicated test system. (5) discusses the basic principle of laser optical axis correction and methods of instruction designed laser target device optical axis correction device addresses the key technologies: large aperture telephoto lens from the axis parabolic reflector design problems, and designed and observation devices can be used for a variety of cross target, the final calibration accuracy .
