According to the characteristics of modern and future battlefield environment,facing the urgent need of information warfare against defensive weapons and equipment in the confrontation environment,aiming at the enemy's long-range,multi-channel and omni-directional precision guided weapons attacks,a multi-band confrontation jamming source with active jamming as the main and passive jamming as the supplement is designed to study the high-load,high-precision and high-speed.The key technologies,such as directional turret design,integrated intelligence processing and command control of concomitant defense,and integrated design of concomitant integrated optoelectronic defense system,have been developed to be able to operate independently.In this paper,the integrated intelligence processing and commmand and control information flow of concomitant defense is studied,and the function of target searching and tracking in the flow is realized.The main contents of the article are:(1)Intelligence processing and command and control module,mainly through receiving air information instructions from superior or independently searching,threat judgment and tracking air maneuvering targets,realizes accurate positioning of low-altitude aircraft,missiles and other incoming targets,guides the integrated jamming countenneasure module to implement effective jamming,and makes the incoming targets lose precision strike.Strike ability to protect important targets.(2)According to the operational mode of integrated optoelectronic defense system,3 mrad divergence angle laser directional jamming is used as the main means to continuously track and jam optoelectronic sighting equipment or optoelectronic guided weapons.The overall technical index of the system response time is not more than 11.8s,and the response speed,tracking accuracy and stability to the intelligence processing and command and control module are also discussed,has put forward higher requirements.(3)Achieving fast acquisition,stable tracking,precise pointing and high-efficiency jamming of the target,carrying out multi-target data association processing,multi-source information fusion processing and threat assessment and judgment,acquisition and tracking smooth switching control,aiming and tracking matching control and other key technologies to achieve the functions of the process,and carried out.Test verification.(4)According to the analysis of the test data,it can be seen that the precision of the system target detection and tracking equipment is 0.283 mrad,which meets the target detection and tracking accuracy 0.3 mrad.The radar can detect the target accurately and build navigation.The system can transfer the search and tracking process smoothly,the infrared image tracker can track the target stably,and the system can track the target correctly.The tracking accuracy of air targets is less than 1mrad,which meets the design requirements of the system.The design and implementation of command and control module of an autonomous electro-optical defense system is completed.
