Max. Phase Deviation
- Average electrical phase jitter between
samples inside an echo from a single target must not exceed the
max phase deviation setting where max phase deviation is set in
units of phase steps (128 phase steps = 180 electrical degrees).
Recommended setting is 2 - 3 for normal conditions. For weak
echoes in noisy conditions you should allow for more jitter (4 -
10).
Max. Gain Compensation
- The correction value returned
from the transducer gain model must not exceed the maximum
gain compensation setting. (This is the one-way maximum gain
compensation. The two-way maximum compensation will be 12
dB). All single targets outside the angle corresponding to the
chosen gain compensation are skipped. Thus one can reduce the
sample volume (beam angle) by choosing a lower value for
maximum gain compensation.
Min Echo Spacing
- The is the minimum spacing between two
single echos required for acceptance.
Calibration
Click the
Calibration
button to start the dedicated calibration
program with single target detections for this layer.
Note that you must click
Apply
or
OK
before you start the
calibration program if you have made changes to the single
target detection parameters. This is to ensure that the parameters
have been applied for the layer.
