Means and Methods for Decoupling of Receiving and Transmitting Paths of Nonlinear Baseband Pulse Radar

To obtain information about the scattering of nonlinear ultra-wideband signals by objects, we need to study methods for decoupling of receiving and transmitting paths in the receiving system of nonlinear baseband radar. This paper proposes possible methods for decoupling of the receiving and transmitting paths in the system, presents an experimental study and improvement of these methods for a more thorough selection of test signals in the receiving system of the radar. Further, the study of nonlinear objects detecting by the prototype of nonlinear baseband pulse radar using the combined receiving and transmitting antenna is considered.
