Jamming Effectiveness Evaluation of Active Radar Seeker Based on Rough Set

In modern air combat, active radar guided missile has become the main threat for fighter's safety, an accuracy evaluation on jamming effectiveness of active radar seeker can provide support for pilot to choose jamming measures. Traditional evaluation methods have drawbacks that many uncertain factors and easily effected by subjective factor. To overcome the drawbacks, this paper, based on knowledge database, adapts to rough set to reduce attributes and extract decision rules which is the used to evaluate current jamming measure. The algorithm, which is not affected by subjective factors, not only cuts down evaluation time but also improves the objectivity and real time. Data to be evaluated is simulated via simulation case, and the feasibility and effectiveness are verified.
