Abstract


Optical tracking system has become the artillery, aircraft, missiles and warships in the eyes and nervous \Therefore, the detection of the optical tracking system is particularly important. However, if you use the real goal is to provide weapons test signal, not only to spend a lot of manpower, material and financial resources, and may also extend the weapon's development cycle, and even in some cases can not be achieved. For this reason, now widely used in the target simulation debugging techniques for the detection of the optical tracking system. Galvanometer laser scanning moving target simulation system designed in this paper is used to detect optical tracking system for a ground-based anti-aircraft weapons, which are able to simulate in the laboratory according to the target movement and state of motion the available photoelectric tracking the moving target. Subject galvanometer laser scanning moving target simulation technology, the laser beam after dual galvanometer total reflection spot scanning the target trajectory on the projection screen, the spot is analog optical tracking system to track simulated moving target, it has The real goal of visible light and infrared features. This paper discusses the development status of a moving target simulation technology at home and abroad, and then analyzed the principle of laser scanning galvanometer moving target simulation technology, quadratic curve fitting algorithm to eliminate pincushion distortion, and derivation of the target uniform radius exercise the three simulated target trajectory route mapping algorithm. On this basis, according to the system functions and technical specifications, design the overall system program, including the four parts of the system control, system scan, the circuit of the system hardware and system software. System control program using PC, ARM microprocessor master-slave control mode, PC machines focus on system management work of the man-machine interface and send control commands ARM microprocessor handles all the details of the implementing agency control; system using vector scanning mode for scanning; system hardware circuit design S3C2440AARM microprocessor as the core, the design of the control center circuit and data storage, the galvanometer control and optical power control unit circuit; system software design based on the C language and point-by-point comparison linear interpolation algorithm, VisualC 6.0 environment design human-computer interaction process and route trajectory planning process, based on the C language, lower computer software design ADS1.2 environment, and then prepared for the PC and the next-bit machine communication USB program. Finally, install the entire simulation systems using projection static point and goal of uniform slash motion system debugging.
