Land-air man-machine cooperation is an important development direction of manned/unmanned combat mode in the future, in which land-based air defense weapons and UAV cooperative air defense combat can give full play to their respective advantages and expand synergy. Aiming at the problems of land-based air defense weapons have close target detection distance and less interception reaction time; the air defense detection cost of early warning aircraft is high, and there is a risk of casualties, the concept of cooperative air defense between land based air defense weapon and UAV is proposed. A land-air integration cooperative air defense combat style is designed, the target indication information provided by the UAV is transmitted to the land based air defense weapon through data link, and the coming target is intercepted beyond visual range, so as to realize the purpose of "discovery and intercept as far as possible".
