Abstract

The invention discloses a robust trajectory planning method for an unmanned aerial vehicle under a non-determined interference environment. parameters; construct the trajectory planning problem of the UAV system; then adopt S‑Procedure and continuous convex optimization algorithm to iteratively optimize the above problem until the algorithm converges; The aircraft carries out trajectory planning and completes the robust trajectory design of UAV communication. The beneficial effects of the present invention are that the invented robust trajectory planning method for unmanned aerial vehicles can improve the quality of received signals on the premise of satisfying constraints.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle communication, in particular to the design of a robust trajectory planning method of an unmanned aerial vehicle in a non-determined interference environment. Background technique [0002] With the rapid development of UAV systems, UAV communication technology has gradually become a research hotspot in academia and industry. UAVs improve the success rate of missions and are widely used in military reconnaissance, battlefield assessment, communication relay and other fields. However, due to the limited network resources available to UAVs, UAV communication faces severe challenges. On the one hand, due to the booming business and the highly uncertain battlefield environment, UAVs need to quickly make trajectory planning in a very short period of time, which tests the timeliness of communication; on the other hand, UAV combat data The transmission link is easily affected by external ...
