Scientific paper

A new object-rotational-scan holography similar in scanning to the rotating-target-imaging technique used in radar astronomy is described. However, its particular method of recording permits imaging even targets which are less distant than planets. The analysis is simplified by considering a one-dimensional system. High-resolution images are obtainable due to wide recorded area. In particular, the recording method through sinusoidal scaling is useful to construct a lensless Fourier transform hologram in a microwave region. The validity of this type of holography is verified experimentally. Further investigation in a two-dimensional system is under way.
