Random Meetings at Sea

Abstract

As ownship moves through a sea of targets moving at constant velocity in random directions, it will occasionally meet some of them when the intervening distance becomes sufficiently small. The very fact of meeting is significant in estimating the properties of a met target. We derive joint distributions for the properties of met targets, and show how to sample those properties in Monte Carlo simulations. We also introduce 'instant' target motion analysis in the form of various conditional distributions of target properties, given observations made at the time of meeting.
