Detailed Description

Interferogram processor.

Constructor & Destructor Documentation

◆ CrossMultiply()

isce3::signal::CrossMultiply::CrossMultiply	(	int	nrows,
		int	ncols,
		int	upsample = 2 )

Constructor.

Forms an interferogram by cross multiplication of two coregistered Single Look Complex (SLC) images.

Parameters

[in]	nrows	Number of rows of the block of the input data
[in]	ncols	Number of columns of the block of the input data
[in]	upsample	Upsampling factor (by default = 2)

Member Function Documentation

◆ crossmultiply()

void isce3::signal::CrossMultiply::crossmultiply	(	Eigen::Ref< isce3::core::EArray2D< std::complex< float > > >	out_ifgram,
		const Eigen::Ref< const isce3::core::EArray2D< std::complex< float > > > &	ref_slc,
		const Eigen::Ref< const isce3::core::EArray2D< std::complex< float > > > &	sec_slc )

Perform interferogram formation on a block of input data.

Computes the upsampled reference and secondary SLCs, cross multiplies the upsampled SLCs and looks down by the upsampling factor to generate the full resolution interferogram.
