Radar processing method and system

A computing device that facilitates processing radar information, the computing device comprises:

• one or more processors;
• and
• a memory in communication with the one or more processors, wherein the memory stores instruction code that, when executed by the one or more processors, causes the computing device to perform operations comprising:
• receiving synthetic aperture radar (SAR) data that specifics a sequence of radar acquisitions of a target area taken over a particular acquisition time, wherein the SAR data comprises a SAR matrix that specifies the SAR data;
• forming a plurality of sub-aperture images, wherein each sub-aperture image is associated with radar acquisitions of the target area taken over a particular interval of the acquisition time;
• determining, based on the plurality of sub-aperture images, velocities associated with one or more target objects moving within the target area;
• and
• generating an image associated with the SAR data that depicts the one or more target objects and the velocities associated with one or more target objects, wherein the operations that involve generating the image associated with the SAR data comprise:
• decomposing the SAR matrix into one or more target object matrices and a background clutter matrix;
• generating one or more target images based on the one or more target object matrices, respectively;
• generating a background clutter image based on the background clutter matrix;
• and
• generating the image associated with the SAR as a composite image of the one or more target images and the background clutter image.
