Abstract

This paper presents a new evolution of SIGNAL´s instrument concept that uses novel Digital Beamforming (DBF) techniques to further extend the coverage of the mission. In addition, by introducing two phase centers in azimuth, which are needed to achieve the swath extension, the system recovers the desired along-track interferometric capabilities.
