Radar confrontation capability evaluation method based on nonlinear SEM

Abstract

The invention discloses a radar confrontation capability evaluation method based on nonlinear SEM. The method comprises the following steps: S1, constructing radar confrontation capability evaluation indexes through the aspects of radar reconnaissance capability, radar command and control capability, radar attack capability and radar combat adaptability; S2, establishing a radar confrontation efficiency evaluation index, reflecting the efficiency generated by the radar in a combat process through the radar confrontation efficiency evaluation index, and establishing a nonlinear structure equation model of radar confrontation capability evaluation according to the radar confrontation capability index and the radar confrontation efficiency index; S3, identifying the nonlinear structure equation model, solving a radar confrontation capability evaluation index and a radar confrontation effectiveness evaluation index according to radar parameters and a radar deduction calculation result, calculating a covariance matrix of a combat effectiveness index in a composition scheme, and inputting the covariance matrix into the nonlinear structure equation model for radar confrontation capability evaluation; and S4, performing parameter estimation on the nonlinear structure equation model.

Description

technical field [0001] The invention relates to an assessment method, in particular to a nonlinear SEM-based radar countermeasure capability assessment method. Background technique [0002] Adjudication and evaluation are an important part of radar countermeasure equipment testing. The radar countermeasure equipment test adjudication is to comprehensively use the test data of both parties and the requirements of equipment tactical and technical indicators, and compare the signal parameters item by item according to the adjudication rules to judge the results of tactical countermeasures such as radar countermeasure equipment test reconnaissance and interference. The test evaluation of radar countermeasure equipment is to comprehensively utilize the test data of both parties and the judgment results of tactical confrontation behavior, and evaluate the overall tactical and technical performance of the equipment through statistical analysis, index calculation, result evaluation ...

AI Technical Summary

Problems solved by technology

The traditional adjudication and evaluation operation method of electronic countermeasure equipment testing is mainly based on ex-post adjudication and evaluation. There are situations such as lagging behind in the development of operation methods, high subjectivity in adjudication evaluation, difficulty in timely analysis and discovery of problems, and untimely feedback of results, etc., which weakens or even destroys to a certain extent. The impartiality of the judgment evaluation results

At the same time, due to the different purposes, objects, and subjects of various types of radar countermeasure equipment tests, there are large differences in the content, standards, and methods of test ruling evaluation. Adjudication evaluation creates a complex and repetitive workload

The uncertainty faced by the evaluation of radar countermeasure test verdict has become the main factor restricting the development of radar countermeasure equipment test verdict evaluation means
