Patent ID: 8760634

Claim:
An optical synthetic aperture radar, SAR, apparatus comprising: an optical signal source capable of generating a plurality of optical signals, each of the optical signals having substantial energy in a wavelength that is different from wavelengths of other ones of the optical signals; a modulation signal source capable of generating a modulation signal; a transmitter capable of generating an optical amplitude modulated signal by amplitude modulating the optical signals with the modulation signal, and transmitting the optical amplitude modulated signals in a beam at a target; a receiver that receives reflected optical signals resulting from the optical amplitude modulated signals that were transmitted, the receiver including a plurality of light detectors that are capable of detecting reflected optical signals having wavelength ranges substantially the same as the wavelength ranges of the optical signals; and a SAR processor, wherein the receiver outputs a plurality of received signals corresponding to a number of light detectors, the SAR processor inputting and processing SAR-data generated based on the received signals and generating at least one of an image and a moving-target-indication.
