  • Method and apparatus for locating a target using an autonomous unmanned aerial vehicle
    Patent number: 9696430
    Abstract: Described herein is an unmanned aerial vehicle (UAV) system that incorporates sensor data to statistically minimize the time to autonomously locate a target on the ground. The system uses a two-stage approach to finding the RF target: 1) randomized flight, such as Lévy fight, to search the ground space and, 2) a geo-localization process, such as a simplex minimization process, to home in on the target.
    Type: Grant
