Let A be the set of samples s in the analysis domain being considered. Then:
|
where
= The mean range of samples in the domain , range_mean (m) = The range of sample s in the domain (m) = 0 if sample s is not in the analysis domain 1 otherwise, including below threshold data.
Depth_mean is the projection of Range_mean onto the vertical axis taking transducer geometry into account. For a vertically mounted transducer pointing directly downwards, Depth_mean and Range_mean differ by the transducer draft only.
