Theoretical TS of calibration sphere R script of function for band averaged TS of tungsten carbide spheres translated from Matlab code (Version date 31/5/05) written by D. MacLennan (Marine Lab, Aberdeen) updated from R version written by Sascha F?ssler 03/2010 updated Sven Gastauer 04/01/2017

Description

Theoretical TS of calibration sphere R script of function for band averaged TS of tungsten carbide spheres translated from Matlab code (Version date 31/5/05) written by D. MacLennan (Marine Lab, Aberdeen) updated from R version written by Sascha F?ssler 03/2010 updated Sven Gastauer 04/01/2017

Usage

ts.cal(
  freq = seq(38, 200),
  c = 1500,
  d = 38.1,
  mat = "TC",
  water = "sw",
  rhow = NULL,
  plot = TRUE
)

Arguments

freq	numeric frequencies [kHz]; default seq(38,200)
c	numeric ambient soundspeeds [m/s]; default 1500
d	numeric sphere diameter [cm]; default = 38.1
mat	string material properties of the aphere Cu = Copper, TC = Tungsten-Carbide; default 'TC'
water	string either sw= seawater or fw = fresh water; will be ignored if rhow (density of seawater is defined); default 'sw
rhow	numeric density of ambient seawater, if NULL parameter water will be used; default NULL
plot	boolean TRUE/FALSE if plot should be part of the output; default TRUE

Value

dataframe with columns "F","TS","ModF2","c", where F = Frequency [kHz]; TS = TS [dB]; ModF2 = ModF^2 and c soundspeed [m/s], an optional ggplot can be part of the output

Examples

ts.cal(freq=seq(90,170,by=0.1),c=1500.5,rhow=1.02509,plot=TRUE)
