In arnejohannesholmin/sonR: Library for reading, processing and converting sonar data to the TSD format
getFanWidth R Documentation
Calculates the width of a 2-D sonar fan given the specifications in the parameter fanWidth. Only one time step is treated.
Description
Calculates the width of a 2-D sonar fan given the specifications in the parameter fanWidth. Only one time step is treated.
Usage
getFanWidth(data, fanWidth, stretch = 1, range = 0, ind = NULL)
Arguments
data
The list of inputs variables as returned from read.TSD (including ).
fanWidth
Has a number of possible values: (1) "b1": one way beam width. (2) "b2": two way beam width. (3) "fe": beams modeled by rectangular cones with width withing the fan given by the inter-beam angle, and calculated using the equivalent beam angle. This normally causes larged fan width due to overlap between beams.
stretch
Used to stretch the voxels of the ME70 multibeam echosounder in the direction of motion, so that space in between voxels is smoothed out.
range
The range at which this stretch value is as desired
ind
The indices of the beams to treat (such as data$rect).
