Block diagram of a near-field phased array radar system using antenna multiplexing. The purpose of this radar was to prove the concept of imaging through concrete walls at stand-off ranges.

First generation designs of this type of system were called phased arrays since they used the signal phase as the controlling parameter using ferrite cores. I worked with Grumman Corporation in Great ...

The fiber laser array system, developed after more than a decade of research and testing, consists of phase locking and beam combining for multichannel, 7 and 19, fiber laser sub-aperture arrays.
