Dynamic Scattering Analysis of Midcourse Ballistic Targets with Separation Movements

Abstract

In the midcourse trajectory of ballistic targets, warhead releasing and decoy throwing are two of the several types of target separation events. In the early stages, multiple targets are close to each other, and coupling scattering usually leads to variations in the radar cross section and polarization. If these variation features are investigated clearly, the tracking and recognition ability of an early warning radar will improve for ballistic targets. In this study, dynamic scattering of ballistic targets with three types of separation movements is analyzed; and several separation features that promote the action recognition development of midcourse ballistic targets are proposed.
