Abstract : The problem in question consists of determining means of solving the inverse scattering problem where the transmitted field is given and the received fields are measured, and this data is used to discover the nature of the target. The problem of what information can be determined about the body if the scattering matrix (phase and amplitude) is known only over an angular sector and measured in the far field, is studied. Some of the results are presented in the second section. In particular, the necessity of using short pulse measurements to separate out the signals from the various scattering centers is pointed out. The study of the short pulse bistatic measurements is under investigation. For smooth convex surface, particular positions of the scattering body can be obtained. (Author)
