Problems solved by technology

Genetic algorithm and ant colony algorithm are also widely used in the problem of UAV target assignment, but it is easy to produce a solution that does not meet the constraint conditions in the process of solving, although the heuristic information in the constraint can be used to check the solution, But it increases the time consumption of the algorithm, which is not conducive to the timely response of real-time tasks, and is limited to solving the problem of single-machine targeting single-objective, and cannot realize the solution of single-machine multi-objective

Abstract

The invention relates to a method for distributing targets cooperatively attacked by an unmanned aerial vehicle group and belongs to the field of realtime embedding. The method includes: initializing a particle swarm, formulating a fitness function according to evaluation standards, storing fitness values of all particles, judging whether an optimal target distribution scheme is reached or not, and if not, using a random function, a cognitive function and a social function to update the particles, calculating fitness values of current particles, and updating a particle with individual optimal fitness and a particle with global optimal fitness; comparing particle individual fitness values after being updated and global fitness values after being updated with an initial individual optimal fitness value and a global optimal fitness value, evolving to a next generation after all particles are updated, and rejudging whether the optimal target distribution scheme is reached or not. A particle matrix between the unmanned aerial vehicle group and the targets is established, the problem of target distribution of the unmanned aerial vehicle group can be solved quickly and efficiently through constant self learning, single-vehicle to multiple-target attack can be realized, and the method is simple, convenient and quick.

Description

technical field [0001] The invention relates to a method for allocating targets for unmanned aerial vehicle group cooperative attack, and belongs to the field of real-time embedded technology. Background technique [0002] With the continuous advancement of new military reforms, real-time embedded UAVs have developed in the direction of high intelligence, high precision, and collaboration. As one of the key technologies of collaboration, cooperative attack refers to the mutual cooperation between two or more UAVs through the battlefield information network and guidance network to complete weapon strikes and attack ultra-long-range air targets, medium / long-range A new type of attack that strikes distance targets and ground targets. [0003] At present, the fire control and target allocation methods of unmanned aerial vehicles require high real-time performance, and the attack on the target can be completed in the shortest possible time. Genetic algorithm and ant colony algo...
