Compared to the traditional warfare, the future war will be developed into informative, digital and multi-dimensional, not only aero amphibious, but also electromagnetic. In recent years, it's indispensable for battles under the framework of radar network, so it's an important issue how to assign radars reasonably to detect and scout targets; on the other hand, with the wide usage of high-tech weapons, it's also an important issue how to assign weapons to realize fleet's combat effectiveness in large extent.In the background of anti-air warship fleets environment, from the aspect of application, the optimization problems of target assignment in radar network and weapon-target assignment are discussed in this paper as follows.â‘ A mathematical model of target assignment in radar network is established based on Decomposition-coordination method of the Large Scale System Theory. Its main idea is that decomposing m batches of targets into m sub-optimal problems; the coordinator is used to coordinate the solution of each sub problem and the global optimal results, which make the probabilities of target detection maximal in the entire radar network, are obtained.â‘¡B ased on the established evaluation index system of aerial target's threat, Grey Situation Decision of Grey System Theory is presented to solve the evaluation problem, through the mathematical model and arithmetic, simulated experiment demonstrates the idea's flexibility.â‘¢Taking each warship as a combat unit, Simulated Annealing arithmetic is used to assign weapons against targets according to the firepower-equipment, weapons'performance, targets'threat evaluation in each unit.â‘£The idea of cooperative engagement capability(CEC) is imported to this paper, according to the local weapon assignment results produced in each unit, how to coordinate targets assignment of the warship fleet's weapons is researched further, which pursues the global optimal combat effectiveness.Simulated results demonstrate that the serial of ideas proposed in this paper are effective and efficient, they can not only enhance detective ability of the entire radar network, but also reach the purpose of evaluating target's threat exactly and assign weapons optimally to attack targets.
