激光红外多功能复合模拟系统设计研究

Design and Research of Laser and Infrared Multifunctional Composite Simulation System

摘要:

红外制导具有被动成像隐蔽性好、精度高等优点，但是红外制导极易受到激光干扰。另外，由于红外制导不能携带距离等信息，而激光制导正好弥补了这一缺点，因此激光红外复合制导以及相互干扰技术是目前国内外研究重点。在对相关制导、干扰技术进行研究时需进行不同环境下的不同实验，若在现场进行多种实验，造价高且消耗人力物力时间较多，因此可设计一个多功能模拟仿真系统进行不同环境下的多种模拟实验。模拟系统应用了仿真理论、仿真技术、PID控制、图像处理、运动控制等多种技术和控制方法。模拟系统中红外热源温度控制误差为±0.5℃，转台可在±10°和±20°转动范围且角分辨率优于20″，图像采集系统采集图像大小为253×318且连续采集速率为50帧/s。模拟系统可对红外制导、激光制导、激光干扰红外制导等多种制导及相互干扰技术进行仿真实验。

Abstract:

Infrared guidance has the advantages of passive imaging concealment and high precision, but the infrared guidance is easily interfered by laser. In addition, infrared guidance can not carry information such as distance, while laser guidance just makes up for this shortcoming, so the laser infrared composite guidance technology and mutual interference technology is the focus of research at home and abroad. Different experiments in different environments are required in the study of correlation guidance and interference technology. If a variety of experiments are carried out in the field, it will cost a lot of money and consume a lot of manpower, material and time. Therefore, a multi-function simulation system can be designed to carry out a variety of simulation experiments in different environments. The simulation system applies simulation theory, simulation technology, PID control, image processing, motion control and other technologies and control methods. Simulation system of infrared heat source temperature control error is plus or minus 0.5 ℃, rotary table can rotate within ±10° or ±20° and it's angular resolution is better than that of 20 ", the image size of collecting is 253 x 318 and continuous acquisition rate is 50fps/s . The simulation system can simulate the infrared guidance, laser guidance, laser interference infrared guidance and other kinds of guidance and mutual interference technology.
