Research On Performance Evaluation Application Of Integrated Electronic System

Multifunctional integrated electronic system is the development hotspot of electronic countermeasure in the future.This thesis mainly studies the on-line performance evaluation technology of radar,communication,reconnaissance and jamming integrated electronic system.For such a dynamic system with complex functions and various influencing factors,online performance evaluation is of great significance for monitoring system status and assisting operators in decision-making.In this paper,the index system and mathematical model of each function are established.The evaluation model of the comprehensive performance of the system is constructed,and the simulation software is developed to demonstrate the performance evaluation process directly,verifying the feasibility and validity of the established model and the proposed method.The main Tasks are described as following:1.the index system is constructed based on the objective,comprehensive,concise and measurable principles.The mathematical models are established to quantitatively describe its performance.2.The parameters in the mathematical models of each index are classified and screened,and the corresponding measurement algorithm is proposed for the internal parameters that need to be measured or estimated on-line to complete the measurement of each index.The effectiveness of the online measurement algorithm of each internal parameter is verified by simulation.3.This paper introduces the common performance evaluation methods.The fuzzy analytic hierarchy process is used to build the system comprehensive evaluation model,and the entropy weight method is used to modify the weight of each index in the model.The gradient projection method is used to solve the optimization problem of aperture distribution,and the feedback information is given.4.The simulation software of integrated electronic system performance evaluation is developed.The software can generate the corresponding signal,measure its index value,and give the comprehensive evaluation results of the system after inputting the relevant parameters of the integrated system.
