Beams were formed using the amplitude beam tilting scheme on an equivalent 13‐element line array. These beams were tilted in increments of 10° from broadside to endfire. Because of the influence of the baffle, beams which were tilted close to end‐fire exhibited the typical reduction in peak sensitivity. There appears to be no advantage gained by tilting a beam more than 70° from broadside due to these baffling effects. Peak sensitivity relative to the forward beam is reduced 9 dB at a 70° tilt and 11.4 dB at endfire while the −3‐dB beamwidth increases from 16.5° at broadside to 24° at both a 70° and 90° tilt.
