Some characteristics of acoustic array antennas constructed with different horns aretested. The measured antenna directivity patterns are compared with theoreticalpatterns.The effects of wave length , distance between horns,the number of horns andthe air temperature on directivity patterns are discussed.The measured directivitypattern of a 4×4 array basically agrees with the theoretical curve. The comparison ofdifferent types of horns shows that the piezoelectric ceramic tweeter has the bestconversion efficeincy, which is three times of the common horn′s. The reflecting hornYH 5-4 has a good ratio of performance to price,and is suitable for phased array antennamanufacture.
