- 7.In the previous seabed classification experiments using the UAT (See ) a pair of vertically separated spherical projectors were used so that cardioid pulses could be formed to direct a null at the sea surface. However, this limited the lowest frequency to 3 kHz so the decision was made to use FFR's to extend the frequency band down to 1 kHz.Google Scholar
