In wireless power transmission systems, in order to provide maximum possible efficiency in the transfer of power, the receiving element of the system must intercept the greatest possible portion of the transmitted energy beam. By having a planar array of receiver elements that are symmetrically located about a physical center, it becomes possible to determine the location on the array of the center of energy of the incident beam. This information is obtained as follows. Sum the output energy of all the receiver elements to the right and left of the vertical center of the array. Determine the difference and sum of these two amounts. Divide the difference by the sum. The result is an indication of the degrees that the center of the incident beam is off in azimuth. Sum the output energy of all the receiver elements above and below the horizontal center of the array. Determine the difference and sum of these two amounts. Divide the difference by the sum. The result is an indication of the degrees that the center of the incident beam is off in elevation.
