The Data generator operator creates a virtual variable containing data evaluated for a user specified algorithm and settings. The virtual variable has the same ping times and ping geometry as the input operand. The algorithms are:
where:
r' = the uncorrected range r (m) or corrected range R (m) of the datapoint. This is dependent on the selection of TVG range correction and specification of TVG range correction offset which are on the Calibration page of the Variable Properties dialog box for the Data Generator virtual variable.
R = r + TVG range correction offset
Y = Data generator algorithm value evaluated at r' (m)
Constant = the Constant value specified on the Generator page of the Variable Properties dialog box, where:
Sv (dB) is for Sv Output
TS (dB) is for TS Output
Constant (dB) is for Unspecified Output
Constant (linear) is for Linear Output
x = the TVG range coeffcient
x = 20 for Sv Output, when a TVG override value is not specified.
x = 40 for TS Output, when a TVG override value is not specified.
x = TVG override as specified on the Generator page of the Variable Properties dialog box
a = Absorption coefficient (dB/m) specified on the Calibration page of the Input operand Variable Properties dialog box.
Value_at_1m = Specified value at 1m on the Generator page of the Variable Properties dialog box, where: Sv (dB) at 1m is for Sv Output
TS (dB) at 1m is for TS Output
