Research On Jamming Effect Indicators And Disruption Management In Aircraft Penetrating Process

Gulf War has opened the curtain of the electronic information warfare. As an important means of warfare in electronic information warfare, radar countermeasures are playing as more and more important role in modern warfare. Enumerating several U.S. External Wars in21st century, at the beginning of the war, the United States always implemented the aircraft penetration combat missions under the cover of the electronic interference, and precision-guided bomb has been implemented on key military facilities and personnel with "surgical-style" operation. The effect of combat is very obvious. How to implement maximum interference and plan the most optimal penetration route are currently the hot issues of military research at home and abroad. In this paper, a new interference effect evaluation indicator is designed for penetration combat missions, and in the emergency situations the disruption management issues of the aircraft penetration trajectory planning are discussed. The specific contents are as follows:First, under the deployed situation of multi-level radars and in the assumed electronic warfare environment, the evaluation principles of radar jamming effect are discussed in detail. Based on the radar interference effect, the evaluation conditions are presented. On this basis, the membership function of three interference effect evaluation indicators (the interference level indicator, the interference distance indicator and interference angle indicator) is designed. Several models of active suppression jamming are presented. The radar jamming effective decision-making matrix is built by new interference effect evaluation indicators. On this basis, dynamic programming algorithm is used to distribute radar jamming resources with one radar and one jammer for the aircraft penetration trajectory planning in later aircraft penetrating process.Second, on the basis of simulating threatening regional and rasterizing battlefield environment, the issue of the aircraft penetration trajectory planning is solved by opportune cost indicators and an ant colony algorithm based on penetration path, which has been improved in this paper. The improved ant colony algorithm, the basic ant colony algorithm and adaptive ant colony algorithm are compared in the experiment. The experimental result has demonstrated the improved algorithm is useful in the issue of the aircraft penetration trajectory planning. Third, on the basis of the global route planning, the real time disruption management issue of the aircraft penetration trajectory planning is discussed. After the brief introduction to the basic knowledge of the disruption management, the real time disruption management issue of the single aircraft and the formation aircraft are discussed and simulated, including the penetration endpoint changed, the mid-point refueling, and route blocked..Finally, according to the study of this paper, a system of aircraft penetrating is designed with MATLAB tool. This system can distribute the radar jamming resources according to the given basic parameters, and at this time it can show normal and emergent penetration path planning results in the two-dimensional display manner, three-dimensional display manner and dynamic display manner.
