Abstract

A 3-dimensional kinematic ranging algorithm for IRSTs is described, capable of real-time operation at greater than 25 Hz. The algorithm implements two 2-dimensional extended Kalman filters to estimate range in azimuth and elevation which are then combined to give the 3-dimensional range. Also included are algorithms for target manoeuvre detection and for determining the confidence of the range estimate. Simulation results for the algorithm are presented, which show that accuracies of better than 20% can be achieved at long range, depending on the measurement accuracy.
