Multi-lithic phased array architecture for airborne sense and avoid radar

摘要

Transmit and receive Ku-band phased array designs are described for testing an airborne sense and avoid radar. The arrays are small with a size of 24 cm × 9 cm and operate from 13 to 17 GHz with electronic scanning from plus or minus 45 degrees in azimuth and plus or minus 30 degrees in elevation. A novel design architecture allows the use of multiple multilayered printed circuit boards and simple air cooling.
