Radar interference effect evaluation method based on fuzzy mathematics and MATLAB graphical user interface

Abstract

A radar interference effect evaluation method based on fuzzy mathematics and an MATLAB graphical user interface belongs to the field of radar interference effect evaluation, is used for solving the problem of radar interference effect evaluation, and is characterized by comprising the steps of: establishing a radar interference factor set and an evaluation set; inputting the parameters of a target radar and a current radar on a MATLAB graphical user interface, and obtaining the interference benefit value of each interference factor in the radar interference factor set through different preset calculation methods; determining a membership function, and performing single-factor evaluation on each factor to obtain a fuzzy relation matrix; obtaining a weight value of an interference factor input by a user; and obtaining a fuzzy comprehensive matrix of the interference factors according to the fuzzy relation matrix and the weight, obtaining a final radar interference effect evaluation result by adopting a maximum membership degree principle, and displaying the final radar interference effect evaluation result on the MATLAB graphical user interface. The data visualization capability of evaluating the radar interference effect by using the MATLAB is improved, and the radar interference effect evaluation process is more operable.

Description

technical field [0001] The invention belongs to the field of radar interference effect evaluation and relates to a radar interference effect evaluation method based on fuzzy mathematics and a MATLAB graphical user interface. Background technique [0002] Radar countermeasures play an important role in modern warfare. A typical radar countermeasure system mainly includes three subsystems: electronic countermeasure reconnaissance, jamming, and command and control. Among them, the radar countermeasure command and control subsystem needs to adjust the jamming strategy according to the reconnaissance information and the jamming effect to achieve the best jamming effect. Therefore, research on jamming effect evaluation technology, accurately judging the battlefield environment and accurately evaluating the radar jamming effect has an important impact on the outcome of the war and has important military application value. [0003] Radar jamming effect evaluation is a multi-index ...
