•
Transmit beam steering, along
: Stabilised for pitch and yaw (±10 degrees)
The transmit fans may be electronically stabilised for pitch and yaw movements in
order to always point vertically. Pitch, yaw, heave and the applied stabilisation are
fully taken into account when calculating sounding depths and positions.
•
Receive beam steering, across
: Stabilised for roll (±15 degrees)
The receive beams are electronically stabilised for roll. In the near field the receive
beams are dynamically focused to maintain angular resolution even at very short
ranges.
•
Range resolution (defined as cT
eff
/2)
: 10.5 mm at 14 μs pulse
•
Output sampling rate
: Up to 60 kHz (12.8 mm)

Pulse shading
: Hanning

Total pulse length
: 37 to 2450 μs
–
Nominal pulse length
: 25 to 1700 μs
–
Effective pulse length
: 14 to 918 μs (BS footprint)
•
Pulse length, FM
:
The FM pulses are compressed by a match filter at the receiver. The effective pulse
depends on the sweep bandwidth and the pulse shading.

Total pulse length
: 1.5 to 12 ms

Effective pulse length
: 125 to 525 μs
