Bottom Track Commands

The H-ADCP uses these commands for "range" to boundary applications. For example, the HADCP is
swept at various tilt angles. The goal is to directly measure the x-sectional area and maximum depth in the
middle of the channel.
The H-ADCP is NOT designed for moving vessel Bottom Track applications.

Available Bottom Track Commands

This section lists the most often used Bottom Track commands.

Bottom Track Command Descriptions

BA - Evaluation Amplitude Minimum

Purpose Sets the minimum value for valid bottom detection.
Format BAnnn
nnn = 1 to 255 counts
Range
Default BA30
Recommended Setting. The default setting for this command is recommended for most
applications.
Description BA sets the minimum amplitude of an internal bottom-track filter that determines bot-
tom detection. Reducing BA increases the bottom-track detection range, but also may in-
crease the possibility of false bottom detections.
Min Size (dm), Near (dm), Far (dm)
EAR-Controlled Technology Subject to Restrictions Contained on the Cover Page.
