This paper investigates the performance and robustness of the space-time integration technique 'by applying it to two different scenarios; a target moving in a straight line through a sonobuoy eld; and a target undertaking a major course change.Although most techniques will track a target moving in a straight line quite successfully many have dif culty tracking the target as it manoeuvres through a slow turn.The performance of this approach is compared with the more traditional extended Kalman Filter algorithm where the advantages and dis-advantages of each technique is highlighted.Results are presented for scenarios using both simulated and sea trial data.1.
