Linear 3D events
Create 3d linear events given propagation velocity, intercept time, angles, and amplitude of each event.
- Parameters
- x
numpy.ndarray
space axis in x direction
- y
numpy.ndarray
space axis in y direction
- t
numpy.ndarray
time axis
- v
float
propagation velocity
- t0
tuple
orfloat
intercept time at \(x=0\) of each linear event
- theta
tuple
orfloat
angle in x direction (in degrees) of each linear event
- phi
tuple
orfloat
angle in y direction (in degrees) of each linear event
- amp
tuple
orfloat
amplitude of each linear event
- wav
numpy.ndarray
wavelet to be applied to data
- x
- Returns
- d
numpy.ndarray
data without wavelet of size \([n_y \times n_x \times n_t]\)
- dwav
numpy.ndarray
data with wavelet of size \([n_y \times n_x \times n_t]\)
- d
Notes
Each event is created using the following relation:
\[t_i(x, y) = t_{0,i} + p_{x,i} x + p_{y,i} y\]where \(p_{x,i}=\frac{1}{v} \sin( \theta_i)\cos( \phi_i)\) and \(p_{x,i}=\frac{1}{v} \sin( \theta_i)\sin( \phi_i)\).
