| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | UWB radar systems, which possess the high range solution, are expected to be applied to a variety of areas with fast imaging algorithms, such as SEABED method. This method makes it possible to image 3-D unknown targets by using a reversible transform after extracting the curved surface, called quasi-wavefront, which is constructed from antenna position and distance to the target. However, in case of observing complex-shaped targets, a more advanced algorithm is required in order to extract them correctly, because the received signals interfere each other with the echos from multiple reflected points. We have already made it possible to obtain the accurate image of complex objects by treating the problem as an optimization with an evaluation function regarding the waveforms. The conventional study, which assumed the simple model that scattering waveforms are known and constant, is not enough as the real-environmental signal processing algorithm. In order to adapt to the real environmet, we propose to consider the waveforms into the evaluation function, which depends on the antenna pattern and its frequency property. We obtain the accurate image by appling the real observed data of multiple objects. | |
