Objective Measurement Method for the Confidence of Track Quality and Effectiveness Evaluation of Tactical Data Link

Aiming at the problem that the reliability of track quality and effectiveness evaluation of tactical data link system can not be objectively measured at present, an objective measurement evaluation confidence method is proposed. This method describes the evaluation confidence from three aspects: evaluation index, evaluation model and single sample classification confidence. In calculating the confidence of evaluation data, the confidence of evaluation data is determined by analyzing the uncertainty of evaluation data; In the aspect of calculating the confidence of evaluation model, the accuracy of pattern classification is transformed into a measure of confidence of evaluation model; In the aspect of calculating the classification confidence of single sample, according to the distribution relationship of different samples in high-dimensional space, a classification confidence calculation method suitable for most classification algorithms is given; Further, the above three aspects are integrated through the confidence propagation model to obtain the comprehensive evaluation confidence. The simulation results of radar anti-jamming effectiveness evaluation confidence show that this method does not use expert experience knowledge, and can objectively measure the confidence of effectiveness evaluation, and its results are not affected by the evaluation subject, which solves the problem that different experts give different confidence of effectiveness evaluation for the same equipment; Compared with the existing subjective methods, the accuracy is improved by 10%.
