ABSTRACT:
Compensation for a failed element of an active antenna array is acheived by turning the failed element off and selecting a plurality of adjacent, properly working elements as local compensators. A selected voltage and phase increment is then added to the complex output voltage which each local compensator would normally produce. The magnitude of the voltage increment is selected by dividing the magnitude of the failed element's voltage, were it not failed, by the number of compensators. The phase increment is selected to scan the associated voltage increment at a depression angle of about 30 degrees below the horizon.
