Abstract:

The report contains the results of a program to develop and build an electronically steerable MIC linear array with a single MIC receiver front end and the necessary array feed structure. The linear array consisted of four modules in a single housing bolted to a second housing containing four cylindrical waveguide antennas. Phase shifters for beam steering and polarization diversity were tight-coupled meander line, nonreciprocal ferrite structures flux driven to obtain effectively 4-bit operation. A varactor tuned MIC Gunn oscillator was investigated for use as the local oscillator. A new design approach consisting essentially of lumped tuning elements was used. A mathematical model for this approach was generated and computerized. A new design approach in phase shifter flux drivers using standard commercial components was derived. Modified author abstract
