The use of beamforming technology for long-distance underwater acoustic communication systems can improve the received signal-to-noise ratio. In order to analyze the application of beamforming technology in underwater acoustic communication, the paper presents SWARRAY, a broadband constant beamwidth beamforming software for arbitrary array. Based on the improved adaptive beamforming method and time-domain wideband beamforming technology, the software can synthesize the output signals of the array under various motion conditions and provide a basis for evaluating the application performance of the beamforming technology in the underwater acoustic communication system under the actual channel conditions. Combined with the direct sequence spread spectrum scheme, the validity of design software in underwater acoustic communication simulation is verified.
