Real-time evaluation method for anti-interference performance of radar

Abstract

The invention belongs to the technical field of radar, and in particular relates to a real-time evaluation method for anti-interference performance of radar. The method comprises the following steps: firstly analyzing technical and tactical indicator change of the radar in an interference environment; selecting an initial indicator to establish an initial indicator system; then reducing the initial indicator system through a rough set attribute reduction method; establishing a basic indicator used during final evaluation of the performance; establishing a fuzzy analytical hierarchy process-based anti-interference performance evaluation model of the radar; obtaining a group decision matrix through a Delphi algorithm; then ordering the decision matrix by using a chi-square least square method; constructing a final comprehensive weight vector to finally obtain the anti-interference performance result of the radar. Through the method, the anti-interference performance of the radar is more accurately evaluated, the interference mode in the real-time environment can be recognized by using an interference type recognition algorithm, and the corresponding evaluation model is automatically selected to calculate the anti-interference performance of the radar, so that the performance loss of the radar in the real-time interference environment can be obtained.

Description

technical field [0001] The invention belongs to the technical field of radar, in particular to a method for real-time evaluation of radar anti-jamming performance. Background technique [0002] Anti-jamming performance is one of the important tactical and technical indicators of radar systems. However, there is no recognized and universal measurement standard. Most radar engineers explain or describe the anti-jamming performance of the system from a qualitative point of view, rather than quantitatively. fully described from the point of view. [0003] In fact, it is complicated and difficult to evaluate the anti-jamming performance of the radar system. Because the anti-interference performance of the radar system is reflected in the electromagnetic interference environment, a comprehensive and accurate evaluation of the anti-interference performance of the radar system must involve various electromagnetic interference environments, and the electromagnetic interference envir...
