ABSTRACT:
A system and method are disclosed for dynamically sizing sectors of a multi-sectored radiation pattern. The disclosed invention teaches the use of multiple narrow beams composited to form a radiation pattern. Signals associated with each such narrow beam may be provided to inputs of a scan receiver or signaling radio which inputs are associated with a particular sector of the radiation pattern. The number of narrow beam signals provided inputs associated with a particular sector defines the azimuthal width of that sector. By altering the number of narrow beam signals provided each such input, the azimuthal width of the sectors may be adjusted. The disclosed invention also teaches the use of attenuators in the signal path between the narrow beams and the scan receiver or signalling radio. By adjusting these attenuators, the effective length of the sectors may be adjusted.
