Coherent Multilateral Radar Processing for Precise Target Geolocation

Abstract

This paper analyzes the target geolocation performance of coherent processing of target signals observed by several radar receivers in a multilateral configuration. Each radar sensor is designed with a sufficient bandwidth to support good target range resolution but without the benefit of a narrow radar antenna beam for useful cross range measurement of the target position. The analysis results demonstrate the ability of coherent multilateral radar signal processing to achieve accurate target geolocation via triangulation and to eliminate target ghosts in a dense, multiple target environment.
