Optimization of the Gain Parameters in a Tracking Module for ARPA system on Board High Dynamic Warships

Abstract

The purpose of this paper is to determine the optimal values of the gain parameters used in the tracking module for a highly dynamic warship. The algorithm of the tracking module uses the -- filter to compute accurate estimates and update the state variables, that is, positions, velocity and acceleration. The filtering coefficients ,  and  are determined from set values of the damping parameter, . Optimization is achieved by plotting a range of the damping parameter  against the corresponding residual error and then selecting the best value of ξ with the minimum residual error. Optimal values of the smoothing coefficients are subsequently computed from the selected damping parameter, .
