Abstract
An along-track interferometric SAR (Synthetic Aperture Radar) of the present invention includes a single SAR line and observes a target only once. SAR data derived from a single observation are subjected to look division in order to reproduce two SAR images deviated in time from each other. Interference processing is executed with the two SAR images in order to determine a phase difference. The phase difference is converted to the velocity of the target. This can be done without resorting to any additional hardware.
