Abstract

As a result of interest in imaging strongly scattering targets, the Air Force Research Laboratory is making available to the community sets of data from various targets. We describe a nonlinear filtering technique, namely, homomorphic filtering, which we have applied to recover an image of the target from the backpropagated field calculated from the scattering data. We show new results for targets that other methods, especially linearized methods, are unable to image. While we obtain good images with real data, convolutional effects arising from limited data can sometimes degrade performance.
