| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Ultra-wide band (UWB) pulse radars have an immeasurable potential for high range resolution imaging in the near field and are applicable to 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 increased shadow regions or a false image caused by multiple scattering echoes. In general, a propagation path of a multiple scattering wave is different from that of a single scattering one, then a multiple scattering echo includes an independent information of target surfaces. This paper proposes a 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 the visible range of target surfaces without a priori information of surrounding environment. |
