Collaborative Engagement for Target Identification and Tracking

A method for controlling unmanned vehicles to maintain line-of-sight between a predetermined target and at least one unmanned vehicle. The method comprises: providing an unmanned air vehicle including sensors configured to locate a target and an unmanned ground vehicle including sensors configured to locate and track the target; communicating and exchanging data to and among the unmanned ground vehicles; controlling the unmanned air vehicle and the unmanned ground vehicle to maintain line-of-sight between a predetermined target and at least one of the unmanned air vehicles; geolocating the predetermined target with the unmanned air vehicle using information regarding a position of the unmanned air vehicle and information regarding a position of the target relative to the unmanned air vehicle; and transmitting information defining the geolocation of the predetermined target to the unmanned ground vehicle so that the unmanned ground vehicle can perform path planning based on the geolocation.
