Detailed Description

45-degree phase-shift migration.

Constructor & Destructor Documentation

S2FK45Migr::S2FK45Migr ( float spx )

Default constructor with source point x-coordinate in velocity model observation system provided.

virtual S2FK45Migr::~S2FK45Migr ( )

virtual

Destructs object.

protectedvirtual

Calculates 2d fft for provided wavefield.

virtual bool S2FK45Migr::getImage	(	const WaveField &	wf_up,
		Vel2dModel &	mod2d,
		WaveField &	image
	)		const

virtual

Gets migration image. Returns false on error. Image wave field should be predefined by corresponded sizes (dimension of x, dimension of z).

Parameters

mod2d	Up-going wave.
image	2D velocity model. Resulted migration image.

void S2FK45Migr::setSp ( float spx )

inline

Sets velocity model local x coordinate of SP.

float S2FK45Migr::m_spx

protected

Source point coordinates.
