Simulate a seismic shot

Description

Simulate an exploration style seismic shot with ground roll, air wave, refractions and reflections.

Usage

1
symshot1(PLOT = FALSE)

Arguments

PLOT

logical, TRUE=plot the wiggles. DEFAULT=FALSE

Details

Arrivals are calculated based on geometric considerations with a 1D layered model.

Value

smograms

Matrix: columns are individual traces

dt

x

x locations

dx

spacing in X-direction

REFL

reflection information

REFR

refraction image

GRrec

THEORY

List of theoretical values

trefrac

treflex

reflection arrival times

tair

Air arrival times

velair

velocity for the air wave

mod
