Abstract
Application of the Prony’s method with segmented approach to radioimage analysis is researched. Measuring system with a horn antenna is considered. An optimal geometry of the horn antenna for implementation of Fourier-holography in frequency-time domain is estimated with the help of a big perfect reflector model. The mathematical model of the structure with reflector is constructed and used for initial verification of the method. The model is constructed with the help of the transmission line theory. The Prony’s method is then applied to estimation of distances to the points of radioimages constructed with the help of a computer model of an antenna. Distances on the image of a conductive strip obtained by aperture synthesis are estimated with the help of the method. It is found that estimated distance tends to increase with the increase of the lateral distance from the axis of the antenna. This result agrees with the fact that antenna radiates a non-plain wave. It is important for the aperture synthesis calibration procedure with help of the conductive strip.
