PREDICTION OF SLBM IN-PLANE MOTION UNDER VARIOUS DEGREES OF A PRIORI KNOWLEDGE

Abstract

Observations on the trajectory of an SLBM can be used to estimate parameters of the trajectory and to predict future positions of the SLBM by using standard maximum-likelihood estimation methods. The prediction error is a function of the observation time and the length of time for which the prediction is made, and it also depends on the amount and kind of a priori information available. The prediction error is derived and computed for four different cases as follows: (1) The trajectory is a polynomial in time. (2) The trajectory corresponds too constant-thrust propulsion with unknown thrust parameters. (3) Constant-thrust trajectory with thrust parameters known but time and space origin unknown. (4) Constant-thrust trajectory with only time origin unknown. In general, the greater the a priori knowledge the greater is the prediction accuracy.
