Waves Command Descriptions

HA – Waves False Target Threshold
Purpose Sets a false target (fish) filter.
Format HAnnn
nnn = 0 to 255 counts (255 disables this filter)
Range
Default HA255
Recommended Setting. The default setting for this command is recommended for most applications.
Description The H-ADCP uses the HA-command to screen water-track data for false targets (usually
fish). HA sets the maximum difference between echo intensity readings among the four
profiling beams. If the HA threshold value is exceeded, the H-ADCP rejects velocity data
on a cell-by-cell basis for either the affected beam (fish detected in only one beam) or for
the affected cell in all four beams (fish detected in more than one beam). This usually oc-
curs when fish pass through one or more beams.
