Abstract :
The problem of maintaining a high-performance phased array radar antenna is discussed. Special emphasis is placed on the performance assessment of an airborne phased array radar antenna relative to effects of structure deformation and element outage. Initial discussions are on relevant radar performance evaluations relating to antenna characteristics on the radar system level functional requirements. Major problem areas of maintaining an airborne phased array radar antenna are identified. These include antenna structure deformation due to thermal and vibration environments and array element outages. Results of computer simulations of these effects are summarized. Some considerations for developing an effective maintenance strategy for a high-performance radar antenna are also presented.<>
