Abstract : This program is a follow-on effort continuing the development of the MAIR antenule. This phase of the effort involves development of requirements for the antenules in an active aperture array for airborne radars; front end receiver and power chain development. The successful development of an all X-band module will allow the creation of an airborne radar system with neither high voltage nor mechanical gimbal. The all solid state, low voltage system will greatly enhance the system reliability and maintainability. Each of the individual modules will only have to handle relatively low RF power (two to five watts peak). The low power requirement allows the use of electronically controlled PIN diode type phase shifters. These phase shifters can be exercised rapidly -- less than one microsecond. This high speed beam steering allows ample flexibility for multiple target, spot jamming while search, and separate transmit and receiver beam portions, as well as other multiple antenna beam functions.
