Cooperative Geolocalization

Unlike the bigger UAVs, such as Global Hawk and Predator/Reaper, small UAVs offer immediate, in field organic intelligence, surveillance, and reconnaissance (ISR) capabilities to soldiers on the ground. Typically, these small UAVs do not contain sophisticated sensors and fly low which can be both advantageous and limiting to operating units. For reconnaissance missions with a single stationary or mobile target, the ability to fly low and provide persistent “look” of the target is effective using a small UAV. However, the field of view is limiting since the aircraft typically flies low. As missions become more complex involving multiple mobile targets, it becomes difficult for a single UAV with fixed sensor to collect sufficient information for operating units to make optimal decisions. For such missions, we require systems with a high level of autonomy with flexible sensing capabilities. As scenarios become even more complex involving a large number of targets on the ground, we also will need multiple small UAVs with similar capabilities working cooperatively together, which also introduces additional challenges of cooperative control, sensing, and communication among small UAVs.

In this work we focus on developing cooperative sensor resource management (CSRM) techniques to optimally control, sensor parameters, orientation and position of the UAVs to precisely  geolocate multiple ground moving targets.
