摘要:
A radar system of the type utilizing an optimal estimator to process raw range and angle track data for driving a radar antenna, where the tracking computations, range rate, and angular rate of the range vector are utilized in estimating the target velocity vector and the target acceleration vector. The attenuation inherent in the practical estimation of target acceleration is effectively removed for severely maneuvering targets by a compensating system that provides an attenuation factor, and multiplies the estimated acceleration output signal by the reciprocal of such factor. The implement control system is governed by the estimated target position and estimated target velocity from the estimator, and the modified acceleration signal of the compensating system.
