Imaging from limited-angle backscattered data from strongly scattering targets
Abstract
A measurement technique for collecting scattered field data around a small solid angle in the backscatter direction is described. Given these highpass filtered data, a number of methods that can recover an image of the target, depending on whether the scattering target is strongly scattering or not, are briefly reviewed. Due to the nature of these limited frequency data, a method is described which allows one to incorporate prior knowledge about the target, in order to estimate a reconstruction. The performance of the method is compared against traditional Fourier methods.
