[Abstract]:With the development of laser and optoelectronic technology, various types of laser rangefinder are included. Laser irradiators, laser-guided weapons, free-space laser communications, lidar and other laser systems are widely used in the military field. The common feature of these weapons is that the main technology of these weapons is the use of the characteristics of lasers, good directionality and coherence. As an active light source, interference and electromagnetic wave characteristics solve a series of military tasks, such as target ranging, information transmission, laser guidance and so on. Therefore, laser detection plays a very important role in the research and testing of this kind of system, and is the key technology of system engineering. On the basis of analyzing the technical principle and scheme of laser photoelectricity detection system at home and abroad and combining with the technical requirements of the subject, this paper puts forward the research on laser detection system of field photoelectric target. In order to solve the laser detection technology in the free space laser transmission process, a certain exploratory study has been made to solve the atmospheric laser signal detection technology. Firstly, the basic principle of laser detection technology at home and abroad is analyzed in detail. By comparing the advantages and disadvantages of various laser detection systems, five groups of laser detectors are selected to be distributed on the surface of infrared thermal target, and the probe is used to detect the incident interference laser. It can test the consistency of photoelectricity and laser emission axis of laser jamming equipment, system reaction time and so on. Secondly, according to the principle of reliability and feasibility, the laser detection system is designed. In the hardware design, the relative main devices are compared, and the near infrared detector, microprocessor and other main devices are tested and screened, and the signal amplification circuit, filter circuit, shaping circuit and signal acquisition system are designed. A set of reliable hardware circuit and signal acquisition module are designed. The types of detectors which meet the requirements of the system are analyzed in depth, as well as the performance index and noise type of the detectors.
