Target recognition from limited-angle backscatter data

With a certain number of data points, and a certain degree of detail in one's prior knowledge of a target set, it is possible to determine whether the best course of action is to shape the target or to form an image. To this end, a procedure has been developed that extrapolates these data in k space, thus improving the estimate of the target. By using some examples, it has been shown how to use this method to infer information about the target when very little backscatter data are available.
