Abstract:

The principal objective of this project is to investigate problems associated with achieving the driveread-out system complexity necessary to control a phased array antenna with optical heterodyne techniques. In particular, this work concentrates on multi-channel microwave optical conversion. The approach has been to study the problems associated with device arrays of single sideband modulators that would be necessary to control the amplitudes and phases of all signals delivered to a phased array front end. Our approach remains focused on increasing the complexity of control by modulating only a small number of optical channels which can then be locked to a previously locked active antenna array. This approached is also enabling a better understanding of the accuracy and validity of our computer aided analysis and is also allowing a greater range of device complexity to be analyzed.
