    • A method and apparatus for obtaining high-resolution images of rotating targets by using an image reconstruction algorithm without interpolation, are provided. The method comprises the steps of: a) acquiring initial information; b) calculating parameters; c) computing a start frequency ƒsk and a step frequency &dgr;ƒk; d) measuring data for the target to store them; e) determining whether or not the step d) is completed; f) if the determination result is negative, repeating the steps a) to e); and, if otherwise, obtaining the image; and g) displaying the image. The apparatus comprises means for rotating the controllable target by a predetermined angle; means for generating a first signal; means for transferring the first signal to the controllable target; means for receiving a second signal reflected from the controllable target; means for converting the first and the second signal into a third and forth signal, respectively; and means for processing the third and forth signal to reconstruct an image representing the controllable target, and for controlling the rotating means.
