Abstract

The classical approach to objective evaluation of radar performance utilizes appropriate forms of radar range equation to compute the radar range versus different detection probabilities for a given false-alarm probability. This approach implies full prior knowledge of radar system parameters, losses, and signal processing as well as accurate specification of the environment, whether it is a clear or an ECM one. The classical approach involves heavy computations and analysis and the evaluation is environment dependent. The present paper generalizes an approach started by Nengjing in 1985 for deriving formulas for calculation of radar anti-clutter, anti-jamming, and generalized ECCM capabilities. This new approach avoids most of the problems encountered by the classical one and facilitates comparison of radars with different structures but are candidates for same application. The present paper provides more comprehensive objective evaluation of the potential radar performance with better precision of the expressions for the quality levels. A procedure for assigning technical weights to radars in competition is suggested. Examples are given to show the potential of the proposed global
approach.
