ABSTRACT:
A method and apparatus for remotely sensing the content in a field of view are disclosed. The method includes transmitting a coherent optical signal into a field of view; receiving and detecting a reflection of the optical signal from a portion of the field of view bounded by the platform's boresight; correcting the first instance of the detected reflection; and resolving the content of a plurality of cells in the field of view up to the platform's boresight. The apparatus comprises a radome; an optical signal generator; an optical transmission channel; an optical receiver channel; and a plurality of electronics capable of receiving the representative signal and: correcting the first instance of the detected reflection; and resolving the content of a plurality of cells in the field of view up to the boresight from the corrected first instance of the reflection.
