Analytical Study of Ground-Surface Shielding Characteristics of Selected Road Terrains:Volume 1,Development of Shielding Model and Analyses of Results.

摘要

The mathematical model presented herein allows the user to determine the amount of shielding from munition bursts offered by the ground surface to targets (vehicles,personnel,etc.) on and moving along roads or in cross-country terrains. In the shielding model it is assumed that fragments and projectiles travel in straight-line trajectories;therefore,the amount of shielding offered by the ground surface to a target is calculated along the optical paths between the burst point and selected points on the target. The shielding values given by the model are maximum values. Shielding characteristics in terms of probability of shielding for a point(s) on a target,or in terms of average shielding for a one-dimensional target of a specified height,can be obtained. The model variables include target height,number of target height intervals,locations of five target positions,elevations of six munition height-of-bursts (HOB),and eight horizontal target-to-HOB ranges.
