Abstract
A frequency compensator allows the frequency of a multiple element array to be varied while maintaining a constant separation of the multiple beams output from the array. Since the apparent position of the elements is a function of frequency, by changing the apparent distance in accordance with frequency such that the elements appear to be at desired position, the beamsets may remain relatively aligned as the frequency changes. Both transmitted and received beamsets may be compensated.
