Infrared Guidance Simulation Based On Data Distribution Service

Infrared guidance is a technique that uses infrared detectors to capture and track the energy of the target's own radiation to control and guide missile targets.Because of its all-weather,low demand for meteorological environment,infrared guidance has been an essential technology in the field of precision guided weapons,and will play a more important role in the future of modern warfare and local war.Infrared guidance technology needs to deal with large amounts of data,so real-time processing has become the difficulty of infrared guidance technology.Data Distribution Service(DDS)defines a data-centric publishing /subscription communication mechanism,which is different from the traditional middleware,using a unified programming interface to achieve data dissemination,transmission and subscription,optimizing the distributed System structure,improve the real-time data communication system.Therefore,this paper mainly studies the IR guidance simulation based on data distribution service.Firstly,the principle of data distribution service,including the communication model,architecture and main components of DDS,are introduced,and also how to establish DDS real-time data communication is shown in detail.Secondly the principle of infrared signal detection,including the detectability of the signal analysis and detection signal processing are addressed.After that,the calculation method of infrared detection distance and the method of signal modulation and demodulation of modulation disk are studied.The algorithm of signal extraction of rotary FM modulation is designed,and the simulation of this process is realized.Then infrared image processing,including image preprocessing,infrared target adaptive search and tracking,are discussed.Finally,DDS-based infrared guidance simulation system is implemented,and the movement model of missile and target are graphically displayed.In summary,this project achieved an infrared guidance simulation system,including infrared signal detection,infrared image processing,data distribution services and graphics display trajectory and other modules.
