1. A system for detecting objects in a radar image stream, comprising: a flying vehicle; a radar sensor on the flying vehicle; a processor on the flying vehicle; an object detection module loaded on the processor, the object detection module comprising a deep learning algorithm trained on a plurality of labeled radar image chips; the processor configured to receive a stream of radar image data from the radar sensor, the processor further configured to provide the received stream of radar image data to the object detection module; the object detection module programmed to invoke the deep learning algorithm to process the received stream of radar image data into a semantic label corresponding to a detected object in the stream; and the processor further configured to provide the semantic label to an operational control module onboard the flying vehicle.
