Distributed Satellite System for Maritime Domain Awareness.

A robust multi-baseline along-track interferometric Synthetic Aperture Radar (SAR) formation flying concept is proposed to combine effectively several along-track baseline observations for real-time single-pass acquisition purposes. Simulation results are given to support the feasibility of implementing this acquisition mode with autonomous orbit control, using low thrust actuation suitable for electric propulsion. To improve repeatability, a constellation of this formation concept may combine the benefits of these two distributed satellite systems. A maritime domain awareness application is considered as a hypothetical mission to be solved by this combined approach. [ABSTRACT FROM AUTHOR]
