volx.TSDR Documentation

Calculates the voxel volumes of acoustic instruments implemented in echoIBM (see sonR_implemented()). Usually the volume or area data of one ping is returned, but if muptiple time steps are given in the beam configuration data (specifically for fishery sonars), all time steps are returned if there are changes in the settings between pings.

Description

Calculates the voxel volumes of acoustic instruments implemented in echoIBM (see sonR_implemented()). Usually the volume or area data of one ping is returned, but if muptiple time steps are given in the beam configuration data (specifically for fishery sonars), all time steps are returned if there are changes in the settings between pings.

Usage

volx.TSD(data, esnm = "MS70", var = c("volx", "harx"), fanWidth = "b2")

Arguments

data

is the list of inputs variables as returned from read.TSD (including ).

esnm

is the name of the acoustical instrument, given as a four character string. See sonR_implemented() for the implemented systems. May be given in 'data', and in lower case.

var

is a vector of the variables to return. Currently implemented are "volx" for volumes of the voxels and "harx" for horizontal area of the voxels.

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.
