Capture Region-based Optimal Terminal Engagement Geometry Analysis Considering High-speed Target Information Errors

Abstract

This paper analyzes the capture region (CR)-based optimal terminal engagement geometry during high-speed target interception missions. First, under given terminal engagement conditions, the capture region is defined, and some characteristics of the capture region are analyzed. Next, the optimal terminal engagement conditions of two interceptors are analyzed to maximize the probability of their inclusion in the capture region defined by an uncertain target. Information errors of the target are assumed to be in the form of a normal distribution for the heading angle and target velocity. The optimal terminal engagement geometry is then analyzed considering target information errors, and the results are verified through Monte Carlo simulations.
