Radar Anti-jamming Performance Evaluation Criteria And Methods

Effects of radar ECCM are important indexes to judge radar ECCM and the characteristic of ECCM equipment. It has great practical significant for both radar and jammer to evaluate ECCM effects properly, objectively and easily.In this dissertation, a study is performed about rules and methods of evaluation on effects of radar ECCM.Firstly, the representative methods of radar ECCM are briefly introduced.Secondly, many rules and methods of evaluation on effects of radar ECCM are roundly summarized, and they are also appreciated and analyzed. By the way of constructing the evaluating model for general radar ECCM evaluation and expanding the evaluation indexes, the idea of evaluation is extended.Thirdly, a traditional way of evaluation on effects of radar ECCM based on adding model is studied. And some improvements are set up, which can make the methods more effective.Fourthly, the theory about fuzzy mathematics is applied to the evaluation on effects of radar ECCM, and the fuzzy synthetic models are founded to evaluate effects of radar ECCM. Using the models, computer experiments are made to testify the feasibility of the methods above.Lastly, a model to evaluate effects of radar ECCM ability based on neural network is founded. How to use it in evaluating is investigated according to computer simulations. And the objectivity, practicability and convenience are analyzed and discussed.
