The sum of received power has been suggested as a method for providing improved signal detectability from a plurality of sensors while retaining omnidirectionality. This paper describes an alternative procedure for the two-element case that, while not quite omnidirectional, offers a decided advantage in detection performance over the power sum scheme. It involves taking the logical union of the thresholded power of the sum of the sensor outputs and the thresholded power of the difference of the sensor outputs. A comparison of the two systems is presented and it is shown that the latter scheme is almost always better than the former.
