Cooperative reconnaissance and location algorithm of UAV cluster based on TDOA and FDOA

Abstract： In our country′s marine target reconnaissance and surveillance, UAV positioning technology has the advantages of good flexibility and large positioning range, but in the multi-UAV group coordinated positioning, there are still some problems, such as low positioning accuracy, low efficiency of dynamic route planning and so on.In order to improve the positioning accuracy of UAV fleet, effectively compensate for the blind areas of satellite and radar reconnaissance, and enhance the ability of target reconnaissance and surveillance at sea, this paper studies the cooperative positioning of multiple UAVs and dynamic route planning based on the results of time difference and frequency difference processing of passive signals, and simulates and verifies the model and error analysis. The prospects of cooperative positioning and reconnaissance of multiple UAVs are presented.
