Airborne Active Element Array Radars Come of Age
Background
and Enabling Techniques
Fire control and other airborne radars have experienced major increases in capability and sophistication in the last two decades, boosted by the introduction of powerful digital signal processors; but their uncertain reliability reduces system availability and increases life cycle costs. Their low reliability is due to the use of tube-type transmitters and power supplies. Their lifetime also is limited by wear of moving antenna parts in a high dynamic load environment. Basic physical limits on mechanically-scanned antennas also prevent the instantaneous ...
