timeCorOffset: Constant-offset correction (time) of the GPR data

In emanuelhuber/RGPR: Ground-penetrating radar (GPR) data visualisation, processing and delineation

Constant-offset correction (time) of the GPR data

Description

timeCorOffset applies a time correction to every traces to compensate the offset between transmitter and receiver antennae (it converts the trace time of the data acquired with a bistatic antenna system into trace time data virtually acquiered with a monostatic system under the assumption of horizontally layered structure). If all the traces have the same time-zero, this function does not change the trace but only the time (time scale). If the traces have different time-zero, the traces are first aligned to have the same time-zero (spline interpolation)

Usage

## S4 method for signature 'GPR'
timeCorOffset(x, t0 = NULL, track = TRUE)

Arguments

x	[GPR class] An object of the class GPR
t0	[DEPRECATED] DEPRECATED - NO MORE USED. Instead, set time-zero with either time0(x) <- ... or x <- setTime0(x, ...).

Details

Modified slots

• data: trace shifted to time-zeor. The number of rows of data may be smaller.

• time0: set to 0.

• depth: adapted to a virtual monostatic system. FIXME: not regularly spaced!

• antsep: set to 0.

• proc: updated with function name and arguments.

Value

[GPR class] An object of the class GPR
