Simulation of Distributed Spaceborne Interferometric GMTI Radar Systems

This paper presents a comprehensive simulation-based performance analysis of a distributed spaceborne interferometric GMTI radar system. The system utilizes separated spacecraft to form an interferometric configuration, enabling ground moving target indication (GMTI) capabilities in space-based radar applications. Our investigation involves detailed modeling of system parameters including baseline configuration, signal processing algorithms, and target detection methodologies. Key implementation aspects include: - Simulation of phase coherent processing across multiple spacecraft platforms - Implementation of along-track interferometry (ATI) algorithms for velocity estimation - Modeling of signal-to-clutter ratio (SCR) and minimum detectable velocity (MDV) performance metrics - Integration of space-time adaptive processing (STAP) techniques for clutter suppression Through the distributed spaceborne interferometric GMTI radar system architecture, we demonstrate enhanced accuracy and reliability in target information acquisition, leading to improved system performance and operational efficiency. This research contributes significantly to the advancement and application of space technology, particularly in the domain of space-based surveillance and reconnaissance systems.
