In recent years,with the rapid development of information technology,the battlefield information is changing rapidly,and the electromagnetic environment is becoming more and more complex.In the battlefield,radar has always been a tool used to detect targets,so people are more concerned about its performance in the electromagnetic environment of the battlefield.Usually in the radar electromagnetic environment,not only the accuracy of the relevant effect parameters and the accuracy of the core inducers cannot be guaranteed,but the best time for the detection,analysis and control of the unknown mechanism is greatly delayed.In this context,this paper combines with the actual engineering design of the project,puts forward the design scheme of radar electromagnetic environment effecst mechanism based on BN,and designs and develops the related software platform.The platform aims to provide efficient causal investigation into electromagnetic effect and save a lot of manpower and material resources.The main research contents are as follows.Firstly,the radar electromagnetic environment effect characteristic data is discretized to meet the discrete Bayesian network model selected in this paper.secondly,according to the characteristics of the discretized radar data,the appropriate Bayesian network structure learning and parameter learning algorithm is selected to establish a data-driven model.Then,to solve the problem of low modeling accuracy of traditional Bayesian network,it is proposed to integrate the expert experience in the field of radar electromagnetic environment effects into the Bayesian network.In this way,a Bayesian network model that integrates expert experience is constructed.Finally,the Bayesian network inference algorithm is used to calculate the occurrence probability and model accuracy of the desired characteristic effect nodes.In addition,a method for analyzing the sensitivity of radar electromagnetic environment effect is proposed.According to the above research content,this paper designs and completes the radar electromagnetic environment effect mechanism analysis software platform.The software platform mainly includes the following five parts,loading data module,structure learning function area,parameter learning function area,reasoning and sensitivity analysis area.The system test results show that the radar electromagnetic environment effect mechanism analysis software platform designed in this paper has perfect functions,stable operation,and maintains high modeling accuracy,which meets the technical index requirements of the subject and realizes certain application innovation in the electromagnetic environment field.This paper not only promotes the research of radar electromagnetic environment effect mechanism,but also provides some valuable information for relevant researchers,which greatly improves the efficiency of radar effect mechanism analysis,and further improves the combat capability of radar in electromagnetic environment.
