Unmanned Combat Aircraft To Attack Ground Targets

Air-to-ground attack refers to air-ground battle military operation ,and the battle process is complicated and various, during which the safety of carrier and reasonable use of weapon is considered. And in view of the emphasis of zero loss in modern war. A kind of weapon system which can not only satisfy aircraft campaign plane attack efficiency but also is economical is being looked for in many countries. As a platform of air-ground weapon launch, adapting the air-ground weapon, ucav is the best choice for this requirement.This paper studies the path planning for ucavs passing through threat area ,after that threat evaluation, multi-targets assignment and autonomous air-to-ground attack is accomplished. Firstly, the path planning for single UCAV was proposed using the Voronoi graph and Dijkstra algorithm. Secondly, a path planning method was proposed for the path planning of multiple UCAVs .To study the ways of multi-target and cooperative attack in path planning, a task module based on multi-target attacking was designed by using the UCAV's path as the cooperative variable. Then, the multi-target attacking strategy was introduced. Based on the aforementioned, the paper studied the air-to-ground attacking. In the case of air-to-ground attacking, the threat exponent was proposed. Multi-target assignment strategy was introduced and the targets were distributed to each UCAV. At last, autonomous air-to-ground attack is implemented.Simulation results demonstrate the feasibility of the approach presented here.
