Theoretical radar imaging: from images to hyperimages

A method is proposed to construct radar (or sonar) hyperimages from the knowledge of a backscattering coefficient. 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 non-stationary targets. Such a treatment allows to keep control of the relative resolutions and provides a faster access to the relevant information about the target
