Abstract

The triplet arrays provide the ability to solve the notorious port-starboard (PS) ambiguity problem of ordinary single line array. Cardioid beam pattern is provided by the triplet arrays structure by using the time delay of received signals and noise correlation model. The received noise is composed by ambient sea noise and self noise. The former is made of wind and shipping noise, the latter is made of towed flow noise and electric noise. The PS performance is worse when the flow noise increases. The correlation coefficient of triplet arrays is researched by simulation under different noise conditions. The minimum signal to noise ratio (SNR) of PS discrimination is analyzed for cardioid beamformer and adaptive beamformer. The ability to PS discrimination and anti-noise/jammer of adaptive beamformer is better than cardioid beamformer by processing simulation and trial data.
