Abstract (in Japanese) (See Japanese page) 
(in English) As one of the image processing method of radar sensor it is most typical method that employs synthetic aperture processing. In this paper we investigate radar image of scattering models by using an extension idea of array-factor in antenna theory. Applying the phase difference between each element of the array would become so-called phased array beamformer and then weighting to each element becomes adaptive processing. Also, regarding array factor as near the source, it has been applied to far-field transforming algorithm. Because the sum of each element of the delayed phase signal, we can consider it as a kind of aperture synthesis, also known as DAS (Delay and Sum) especially in the field of ultrasound medical imaging and acoustic fields. We present the imaging using array factor with theoretical near-field calculation of a simple model, like conducting plate. Actually, directly using the measured data is usual, its effect is greater if theoretical evaluation is available.
