The principles and performance of coherent synthetic-aperture radar (SAR) are derived in a new and simple manner based on antenna reciprocity. Noncoherent synthetic aperture antennas in radio astronomy are briefly outlined. The anticlutter performance of SAR is analyzed. In addition, a distinction between translational and rotational inverse SAR (ISAR) is explained.

The synthesis of enormous virtual antennas by the step-wise relative displacement of real, practical size antennas has been seminal to the development of radio astronomy. Synthetic apertures found their first ...
