Abstract
A method for the direct reconstruction of an object from measurements, called scattering data, of scattered waves due to probing waves as emitted by a source. The scattering data is related to a scattering kernel by an integral operator. The image is directly reconstructed by executing a prescribed mathematical algorithm, as determined with reference to the integral operator, on the scattering data.
