ABSTRACT:
An electromagnetic signal processing system (10) comprises a plurality of optical fiber arrays (11, 12, 13, 14, 15and16) each having a cluster of optical fibers with their one ends (40) oriented to receive electromagnetic radiation from free-space, or to transmit electromagnetic radiation into free-space. Received electromagnetic radiation passes through respective array outputs (21, 22, 23, 24, 25and26) and optical delays (50, 51; 55, 56; 65) to the input (68) of a signal detector (69). Transmitted electromagnetic radiation from sources (71, 72) passes through optical delays (50, 51; 55, 56) to array inputs (21, 22, 23, 24, 25and26) so that the one ends (40) of the optical fibers transmit the electromagnetic radiation into free-space.
