US Patent 7348917 Synthetic multi-aperture radar technology

Systems and methods of improving synthetic aperture radar (SAR) system are disclosed. In particular, an example system includes a radar signal radiator configured to transmit radar signal pulses that have a partial bandwidth at a regular interval. The partial bandwidth is a portion of a full bandwidth that said radar signal radiator is designed to generate. The example system also includes a receiver configured to receive radar signals returned in response to said transmitted radar signal pulses, and a processor configured to extrapolate said received signals to said full bandwidth, to thereby create high resolution SAR images.
