Single Target Detection
The Single Target Detection dialogue is accessed from the
short-cut menus in the Single Target Position and the Single
Target Histogram views. It is accessed directly if you press the
middle mouse button while the cursor is positioned inside the
same views.
Purpose
This dialogue is used to set the operational parameters for
detecting single targets within the active layer.
Parameters
Min. Threshold (dB) - The target strength for a single target
must exceed this threshold to be accepted.
Min. Echo Length - For a single target detection to occur the
normalized echo length (echo length between the 6 dB points
relative to the peak value divided by the duration of the
transmitted pulse) must exceed this parameter.
Max. Echo Length - A single target detection requires the
normalized echo length to be less than the max echo length
setting.
