[Abstract]:Using mathematics, operational research, management science, computer technology, artificial intelligence technology, network technology and so on, radar jamming assistant decision system can process massive battlefield information data quickly and efficiently, and draw up jamming alternatives. The auxiliary decision system has the characteristics of comprehensive knowledge, intelligent reasoning, quick reaction and so on. It has great application value in military operations. Especially in the field of invisible battlefield-electronic countermeasure. In this paper, the key technology of radar jamming assistant decision system is studied in the background of field air defense operations. The main work accomplished is: 1, the pulse compression radar is introduced. The technical characteristics, working principle and main applications of three advanced radar working systems, pulse Doppler radar and frequency agile radar, are presented. Based on these, the effective jamming patterns are given according to the different jamming properties. The interference principle and method of each interference pattern are expounded, and the interference effect is given by theory or simulation diagram. The influence of the relative jamming parameters on the jamming effect is also explained. Secondly, the radar target threat ranking is studied. In view of the deficiency of the existing air target threat ranking methods for the supporting combat aircraft, The threat ranking method based on global operational effectiveness is studied, the target threat ranking index system is established, and the index weight calculation method of the minimum deviation fuzzy complementary judgment matrix is analyzed. The threat degree of air targets supporting operations is given by introducing the combat capability improvement rate matrix Q. The simulation results show that the method is more accurate in evaluating the threat of air targets supporting operations. More in line with the actual air defense combat. 3, the jamming effect evaluation is studied. The advantages and disadvantages of several commonly used evaluation criteria for jamming effect evaluation are introduced, and the jamming effect evaluation method based on utility criterion is studied, starting from the operational capability of the jammed radar. The effectiveness evaluation index system is selected, the utility function in decision theory is introduced, the complex number form and the large operator are adopted to calculate the jamming effect of the target radar, which accurately reflects the degree of reduction of the target radar's working ability after the jamming is carried out. That is, for the degree of satisfaction of interference purpose. 4, this paper introduces the composition and main functions of each part of the interference auxiliary decision system, the general steps and the main tasks of each step, and mainly discusses the forming elements of the interference alternative scheme. Considering the preemptive influence of the battlefield situation, such as the balance of forces between the enemy and the enemy, on the decision makers' determination, the paper mainly studies the interfering resource allocation under different decision-making principles, and builds up optimism and pessimism. It is satisfied with the interference resource allocation principle and allocation model under three different decision-making principles. The simulation experiment with genetic algorithm is carried out. The results show that the interference alternatives under different decision-making principles have their own advantages and disadvantages. It provides an important reference for the commander to make decision.
