Abstract

The invention belongs to the airborne radar field and discloses an unmanned plane area coverage single step searching optimization method based on a particle swarm algorithm. The method comprises steps that a monitored area and a feasible flight area of an unmanned plane early warning plane group are set, the unmanned plane early warning plane group comprises M unmanned planes, each unmanned plane is provided with an airborne radar, and each unmanned plane flies in a uniform speed; parameters of the particle swarm algorithm are set; modeling of a flight path of the unmanned plane early warning plane group is carried out; single step searching optimization path planning of the M unmanned planes is carried out based on the particle swarm algorithm to acquire a particle having an optimal fitness function value after K times of iteration, a flight scheme corresponding to the particle is a next-step flight scheme of the M unmanned planes; the monitored area can be effectively covered in real time, and a base is provided for early warning of an unmanned plane group.

Description

technical field [0001] The invention belongs to the field of airborne radar technology, and in particular relates to a single-step optimization method for unmanned aerial vehicle area coverage based on a particle swarm algorithm, which is applicable to the track planning problem of the real-time optimal coverage monitoring area of ​​an unmanned early warning aircraft group. Background technique [0002] Unmanned Aerial Vehicle (Unmanned Aerial Vehicle), referred to as UAV, was successfully developed by the British military during World War I. At first, it was only used as a target drone for training. After World War II, there were many unmanned drones used for wartime training. Scientific researchers conducted special research on these target drones, which pioneered the trend of using drones. . With the rapid development of electronic technology, the role of drones is no longer satisfied with being used as a target drone. Researchers have begun to shift their attention to t...
