Abstract
A synthetic aperture radar (SAR) system includes a transmitter capable of transmitting a pair of signals that each have a predetermined frequency in the optical band of the electromagnetic spectrum. The predetermined frequency can be selected, for example, to provide a level of resistance to at least one of movement of the target, target vibration and optical path length variations, and can further be selected based upon a predefined range and azimuth resolution. The SAR system also includes a receiver capable of receiving at least a portion of the pair of signals that has been reflected off of a target. In this regard, the receiver is capable of processing the reflected portion of the pair of signals based upon a difference frequency between the transmitted pair of signals.
