1. A system for assembling a database of labeled radar image chips for object recognition, comprising:

  • a flying vehicle;

    a synthetic aperture radar device onboard the flying vehicle,the synthetic aperture radar device configured to receive a stream of radio wave signals reflected from a target scene; and

    a processor onboard the flying vehicle,the processor configured to process the stream of radio wave signals received by the synthetic aperture radar device into a plurality of two-dimensional radar image chips, each chip including a set of pixels comprising magnitude and phase information derived from the received radio wave signals,the processor further configured to wrangle at least one of a set of semantic labels from each of the plurality of two-dimensional radar image chips, each semantic label corresponding to an object in the target scene, andthe processor further configured to generate a database of labeled radar image chips as a result of the wrangling.
