System concepts, microwave front-end, data handling design and special circuit design were investigated and analyzed to the point that a comprehensive design can be u5dertaken. The degree, speed, and type of automation consistent with a flexible test-bed model were resolved as well as the realization of several operational tests and procedures needed to overcome the limitations of practical equipment. The specification and design of many YIG devices in the front-end were conducted as were investigation into the satisfactory construction of high-speed tuning techniques for these devices. Ultra-lownoise traveling-wave tubes, YIG-stabilized BWO local oscillators and associated microwave components were studied and their integration into the system delineated. Data handling considerations resulted in an approach which will make use of relatively simple digital equipment with the capability of fully automated programming and data processing any time desired.
