Research On Multi-UCAV Cooperative Mission Planning Problem For Ground Time Critical Target Attack

As one of the most important contents on local wars, TCT attack has become amore and more important pattern of operations. Recent years, we have seen a greatimpact of unmanned combat aerial vehicle (UCAV) on local wars. UCAV wouldprobably become one of the most important weaponry equipment in futureinformation-based wars. With the complication of operational environment, thevariation of tasks, together with the enlargement of conducting space, it is hard for oneUCAV accomplish the mission by itself. So the basic style of UCAV in wars ismulti-UCAV cooperation.Multi-UCAV cooperative mission planning would be viewed as multi-objectiveoptimization, principally satisfying mission requirements and the reinforcement thecooperation of several UCAVs in the constraints of its own capabilities. The core issueof resolving this lies in proper modeling and the design of algorithm. In the context ofmulti-UCAV cooperative tasking planning, the thesis mainly touches upon:1. Based on the characteristics of TCTs, the difficult areas are analyzed andthereupon the paradigm of attacking timely sensitive ground objects are put forwardaccording to the attacking process.2. An in-depth analysis and the formalizing description would be conducted in theresearch and a cost-model of timely sensitive function is presented. In the meanwhile amodel of task allocation is established hence the article attempts to solve the issueutilizing Nash Bargaining Solution.3. According to the theory of dynamic programming, the issue of the trackplanning was transformed into discrete programming. Considering the condition ofconflicts, the cost function with policy iteration was used solving the matter.4. Through simulation experiment, the task allocation based on cooperative gametheory and the path planning policy iteration are verified. The results shows that theallocation planning raised in the article would fully identify relevant areas and meet therequirements of cooperative attacks of multi-UCAVs against ground TCT with a goodreal-time.
