Abstract	Abstract Ultra-wide band (UWB) pulse radars have an immeasurable potential for a high-range resolution imaging in the near field and are applicable to an accurate spatial measurement for rescue robots or security systems. SAR (Synthetic Aperture Radar) algorithm can create an accurate and stable target image in the near field. However, in the case of complex or multiple targets, this algorithm suffers from an increased shadow region or a false image caused by multiple scattering data. In general, a stationary phase path of a multiple scattering wave is different from that of a single scattering one, then multiple scattering data includes an independent information of target surfaces. This paper proposes the shadow region imaging algorithm based on the aperture synthesis for multiple scattering data. The performance evaluations in numerical simulation reveal that the proposed method remarkably enlarges a visible range of target surfaces without a priori information of surrounding environment.
