Embodiment Construction

[0035] Such as figure 2 As shown, this embodiment includes the following steps:

[0036] Step 1, collect training samples and samples to be tested:

[0037] In this embodiment, the credibility analysis of the radar anti-interference effectiveness evaluation is taken as an example, and the collected 140 sets of data are shown in Table 1;

[0038]

[0039] Table 1, Lightning anti-jamming effectiveness evaluation data

[0040] Step 2: Assess model credibility analysis

[0041] Step 2.1: Taking the support vector machine (SVM) evaluation model as an example, there are 75 groups of training samples and 65 groups of samples to be tested, including: 15 samples of the first type, 12 samples of the second type, and 18 samples of the third type , 20 samples of the fourth category. Using the SVM model to predict, there are 10 samples with incorrect prediction results. The predicted results are shown in the table below.

[0042] Error Rate is: 0.153846

Abstract

The invention discloses a radar anti-jamming efficiency assessment credibility measurement realization method. For a relationship between mode classification and efficiency assessment, the efficiency assessment is regarded as efficiency grade classification, and from classification credibility, the assessment credibility is researched. An uncertainty theory is introduced in the method to realize uncertainty processing of test data. A credibility measurement method for an assessment model is obtained through calculation according to performance assessment indexes of the classification model. Multiple single-sample classification credibility calculation methods are fused to obtain a widely used single-sample assessment credibility calculation method, and further through a credibility propagation model, a comprehensive efficiency assessment credibility measurement result is obtained. According to the method, the radar countermeasure efficiency assessment credibility comprehensive analysis can be processed, and a complete analysis process and a corresponding calculation formula are given; and the assessment result analysis demands can be met in most weapon system efficiency assessment.

Description

technical field [0001] The invention relates to a technology in the field of information processing and detection, in particular to a method for realizing the reliability measurement of radar anti-jamming effectiveness evaluation. Background technique [0002] Evaluation credibility is a fuzzy qualitative concept, which represents the satisfaction degree of accuracy and authenticity of evaluation conclusions. In the research on the credibility of the simulation system, the data generated under different simulation granularities are compared with the data generated by the real system, and the similarity with the simulation system is judged according to the data distribution, change trend, data size, etc., and then the credibility of the simulation system is judged. sex. In order to improve the credibility of evaluation, scholars start with the evaluation method, discuss the scientificity and rationality of the evaluation method, and then explain the credibility of the evalua...
