摘要:

Experimental measurements of intensities and beam patterns of a parametric sonar transmitting array are presented. For a mean primary frequency of 720 kHz, secondary source levels up to 90 dB//1 μbar at 1 m were attained at 50 kHz. At this level, however, saturation effects broaden the beamwidth to 8° compared to the unsaturated value of 3°.
