Unified Synthetic Aperture Space Time Adaptive Radar (USASTAR) Concept
Abstract
A novel airborne GMTI radar approach based on adaptive multichannel SAR processing is proposed to improve the surface surveillance sensor performance in detecting slowly moving targets on the ground. The key sensor attributes are broad bandwidth, large antenna array baseline of multiple phase centers, and adaptive array processing over a long coherent integration time interval. This sensor architecture may improve the GMTI sensor capabilities in several aspects 1) Target detection at very low minimum detectable velocity (MDV) 2) Robust adaptive processing to cancel strong ground clutter 3) High sensitivity to detect weak targets 4) Flexible array requirement including sparser arrays 5) Compatibility with SAR imaging applications. The presented sensor architecture is suitable for deployment on a fast, stand-off airborne surveillance platform against weak and slow targets such as dismounted troops, guerrillas, terrorists, and illegal vehicle or boat traffic, both in the clear and under concealment.
