Abstract

A method is proposed to construct radar (or sonar) hyperimages from the knowledge of a backscattering function. Compared to usual imaging, the new feature is to treat on equal footing all parameters characterizing the image: frequency, directivity and position of the bright points in the two-dimensional static case; frequency, velocity, position, and date of existence in the one-dimensional imaging of nonstationary targets. The main interest of such a formulation is to allow the control of the reciprocal relations that are always present in microwave imaging. This possibility can be useful for processing data obtained by today´s wide-band radars
