R: Simulate a seismic shot

symshot1 {RSEIS} | R Documentation

## Simulate a seismic shot

### Description

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

### Usage

    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` | sample interval in time, s
`x` | x locations
`dx` | spacing in X-direction
`REFL` | reflection information
`REFR` | refraction image
`GRrec` | ground roll image
`AIRrec` | air wave image
`THEORY` | List of theoretical values
`trefrac` | refraction arrival times
`treflex` | reflection arrival times
`tair` | Air arrival times
`velair` | velocity for the air wave
`mod` | Layered Model

### Note

MOdel is relatively simple:
