Superresolution imaging applied to ultrasonic scattering

A new method for solving ultrasonic inverse scattering problems is proposed. By focusing a model constraint on the impedance profile the authors find a set of non-linear equations relating the reflection coefficient to the parameters of the model constraint. The non-linear part of the equations can be reduced to a linear prediction spectral estimation problem by means of the Born approximation, and the remaining linear part can be solved using …
