[Abstract]:The stealth target represented by F22 has the characteristics of good stealth and strong maneuverability, which is one of the important challenges for the establishment of a new national air defense early warning network in China. The multi-radar network can detect the airspace from different angles and obtain multi-directional battlefield information. Using information fusion technology can improve the detection ability of this kind of stealth targets. In order to verify the performance of the information fusion algorithm and to effectively manage the resources in the network, this paper is based on the dual structure of information fusion and resource management with feedback. The scheme design and the realization of main function modules of multi-radar netting simulation platform are carried out, and the algorithm of anti-stealth deployment optimization of radar netting is studied. The main research work of this paper is as follows: firstly, the research background and significance of the project are introduced, and the research status of multi-radar networking and distributed simulation technology at home and abroad is summarized. Secondly, based on the requirement analysis of radar netted data fusion simulation system, the overall framework of the simulation system is designed based on the high-level architecture. The main federate members of the federation include target, radar, radar, The fusion center and sensor management, etc., describe the functions of the main federates and the input and output interfaces. Based on the Mak rti software, the function of these modules is realized, and the simulation software platform of multi-radar networking data fusion is established, and the related algorithms are transplanted and tested. Thirdly, in order to realize the static management of radar network, the anti-stealth optimization deployment of multi-radar network is studied. Firstly, a simplified model for detecting stealth targets by single radar is established, and then a two-stage optimization index is established for anti-stealth background. An optimization algorithm combining particle swarm optimization and Powell search is proposed to solve the netted radar deployment optimization problem. The performance of particle swarm optimization (PSO) algorithm and the proposed algorithm are analyzed by simulation, and the effectiveness of the proposed algorithm is verified. Finally, this paper is summarized.
