Abstract
Very large phased array antennas (PAAs), particularly in radar and adaptive receiver applications, require computational capability (for beamsteering, null-formation, imaging, and signal correlation) which is effectively proportional to the square of the antenna size. Here, an approach in terms of parallel processing in the optical domain is presented as a potential solution to this processing bottleneck problem. The defining equations for a PAA system are given, along with the transfer functions for an embedded optical spatial filter control element. Such a control element is shown to have the potential of rapidly reconfiguring a large PAA without the speed penalties associated with conventional sequential addressing methods. A hypothetical PAA with optical spatial filter control elements, is simulated in a computer model, and performance results are presented. (I.E.)
