A real-time evaluation method of radar anti-jamming effectiveness

Abstract

The invention belongs to the technical field of radar, and in particular relates to a method for real-time evaluation of radar anti-jamming effectiveness: firstly, analyze the radar technical and tactical index changes in the jamming environment, select the initial index to establish the initial index system, and then use the rough set attribute reduction method Reduce the initial index system, establish the basic index used in the final evaluation of effectiveness, establish the radar anti-jamming effectiveness evaluation model based on fuzzy analytic hierarchy process, and obtain the group decision matrix through the Delphi algorithm, and then use the chi-square least squares method to make the decision The matrix is ​​sorted to construct the final comprehensive weight vector, and finally the anti-jamming performance result of the radar is obtained. The invention more accurately evaluates the anti-interference performance of the radar, and uses the interference pattern recognition algorithm to identify the interference mode in the real-time environment, automatically selects the corresponding evaluation model, calculates the anti-interference performance of the radar, and can obtain the radar in the real-time interference environment performance loss.

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...
