Probabilistic Model of a Floating Target Behaviour in Rough Seas

Abstract

This note presents the results from modelling of floating target visibility and wave cover in rough seas. Waves on the sea surface can hide a target from observer?s view affecting aiming and ammunition effectiveness. The randomly moving sea surface was modelled using a double peaked wave spectrum. The moving sea surface model was used to estimate height of an object hidden by waves depending on angle of sight, wave direction, significant wave height, target speed and time. Based on this data wave cover frequency distributions were calculated. A possible method of using this data in naval gun performance analysis for armour-piercing, point detonation high explosive, and air burst rounds was suggested.
