Receive center beam widths
11 Seabed will not be 100% insonified when exceeding approx. 140° in equi-distant mode.
12 This is a depth range within which the system is normally operated, from the minimum depth to a depth
value corresponding to the max. swath -50%.
13 This is a single value corresponding to the depth at which the swath is reduced to 10% of its max. value.
14 Max. 5ms at 66kHz for T50.
15 Receive center beam width mean values from far-field simulation. All beam widths measured at -3dB, center
beam unsteered, with a sound velocity of 1440m/s, 30dB Chebyshev shading applied.
