Title: SAR-BASED MONITORING OF NON-VISIBLE OR NON-ALWAYS-VISIBLE OR PARTIALLY VISIBLE TARGETS AND ASSOCIATED MONITORING, CRITICAL SITUATION DETECTION AND EARLY WARNING SYSTEMS AND METHODS
Abstract:
The invention concerns a monitoring method that comprises coupling in an integral manner at least one electromagnetic mirror of passive type (1, 2, 3, 4, 5, 6, 10, 11, 13, 15, 18, 20, 25, 26) with a given target (7, 9, 14, 17, 24, 30) to be monitored and monitoring the given target (7, 9, 14, 17, 24, 30); wherein monitoring the given target (7, 9, 14, 17, 24, 30) includes: acquiring, via one or more synthetic aperture radar (s) installed on board one or more satellites (12, 16, 22, 27, 29) and/or one or more aerial platforms, SAR images of a given area of the earth' s surface where the given target (7, 9, 14, 17, 24, 30) is located; and determining, via a processing unit, a movement of the electromagnetic mirror (1, 2, 3, 4, 5, 6, 10, 11, 13, 15, 18, 20, 25, 26) on the basis of the acquired SAR images.
