Synthetic Aperture GPS Signal Processing for Multi-Platform Antenna Configurations

A. Soloviev, S. Gunawardena

Abstract:	This paper discusses the application of synthetic aperture concepts to multi-platform GPS signal processing. The core component of the proposed technical solution is the exploitation of GPS antenna motion and multi-platform signal integration for synthesizing large antenna apertures. Narrow beam generation capabilities of synthetic apertures can be utilized for interference and jamming mitigation and for producing high resolution radar images using passive receivers of GPS signals. The paper demonstrates the feasibility of synthetic multi-platform signal processing for the case where signals are acquired on two moving platforms by two independent radiofrequency front-ends are used to generate synthetic phased arrays. Experimental results are presented. Both uniform and non-uniform arrays are addressed.
