Overall specifications per Sonar Head
Frequency: 293, 300 or 307 kHz
Maximum ping rate: 40 Hz
Number of beams per ping and sonar head: 160
Number of soundings per ping and sonar head: Up to 254
Beamwidth: 1.5 x 1.5 degrees
Beam spacing: Equidistant or equiangular
Coverage sector: 130 degrees per sonar head
Transmit beam steering:
±
15 degrees in 0.5 degrees steps
alongtrack
Depth resolution: 1 cm
Pulse length: 150
µ
s
Range sampling rate: 14, 14.3 or 14.6 kHz (5 cm)
Beamforming method: Time delay with dynamic focusing in
near-field.
Data storage rate: 50 to 400 MB/h (max at about 5-10 m
depth)
Frequencies of 293 and 307 kHz are normally used in dual
Sonar Head systems.
Receive beamwidth is inversely proportional with the cosine of
the beam pointing angle with respect to the Sonar Head (i.e.
beamwidth is 2.1° at ±45° beam pointing angle and 3.0° at
±60°).
