Computer analysis of remotely detected images for image identification

A computer system for remotely detecting and identifying objects through an orbital synthetic aperture radar satellite system, the computer system comprising:

• one or more computer processors;
• one or more computer readable storage devices;
• program instructions stored on the one or more computer readable storage devices for execution by at least one of the one or more computer processors, the stored program instructions comprising:
• program instructions to process, by a threshold and signature analysis, detected peaks in image data received from the orbital synthetic aperture radar satellite system of an object having an array of elements in a predetermined configuration;
• program instructions to generate a list of objects detections based on the processed peaks;
• program instructions to identify the object based on amplitude, polarization ratio, and polarization phase difference of the image data;
• program instructions to classify the identified object based on the generated list of objects;
• and
• program instructions to output, by a user interface, a list of probable object detections with position coordinates and identifications based on the classified identified objects, wherein the list of probable objects are above or within a predetermine threshold of confidence.

An apparatus for remotely detecting and identifying objects through an orbital synthetic aperture radar satellite system, the apparatus comprising:

• a radar retro directive assembly (RDA) arranged as an array of elements affixed to an object that modifies the amplitude and phase of a retro directed signal from a synthetic aperture radar (SAR) system such that identification of the object is possible in synthetic aperture radar images using an image processing algorithm, wherein the apparatus comprises:
• one or more computer readable storage devices and program instructions stored on the one or more computer readable storage devices, the stored program instructions comprising:
• program instructions to process, by a threshold and signature analysis, detected peaks in image data received from the orbital synthetic aperture radar satellite system of an object having an array of elements in a predetermined configuration;
• program instructions to generate a list of objects detections based on the processed peaks;
• program instructions to identify the object based on amplitude, polarization ratio, and polarization phase difference of the image data;
• program instructions to classify the identified object based on the generated list of objects;
• and
• program instructions to output, by a user interface, a list of probable object detections with position coordinates and identifications based on the classified identified objects, wherein the list of probable objects are above or within a predetermine threshold of confidence.
