Abstract
A method for processing received return signals in a visual synthetic aperture radar (ViSAR) system is provided. The method includes receiving a plurality of pulsed radar return signals over a time period corresponding to a plurality of data frames. From this data, processing is performed to generate a SAR image for each single data frame of the plurality of data frames. In parallel, the radar pulses used to form the image frames are buffered into a longer pulse sequence that is used to perform the detection processing, including identifying targets as having characteristics associated with one or more predetermined motion classes according to phase changes sensed between data frames. A visual indication of targets associated with a predetermined motion class is generated, and overlaid onto one of the SAR images.
