Method for Recirculation of Signals in the Problem of Observation of a Point Object above a Metal Surface

Abstract

Application of ultrawideband centimeter-wavelength signals using recirculation of signals in spatial recirculation loops (emitter–target–element of the receiving antenna–emitter) is analyzed in the problem of localization of the position of a point object above a reflecting metal surface. Determination of the coordinates of object above a metal surface is based on the calculation of a generalized correlation integral in the spectral domain for frequency transmission coefficients of the recirculation loops over all receiving elements with allowance for coordinates of a true object, its mirror reflection, and reference point in space. The results of sounding in the presence and absence of the recirculation are compared.
