The SEABED method, which is an fast imaging algorithm with UWB pulse radar systems, makes it possible to image 3-D unknown targets by using a reversible transform between target shape and antenna position besides distance to the target. The antenna position and distance constitutes a curved surface called "quasi-wavefront". We can directly estimate the target shape with this transform if we can extract the quasi-wavefront from observed data. However, in case of observing complex-shaped targets, it is difficult to image them correctly because the received signals interfere each other with the echos from plural reflected points. Conventional studies, which extracted the quasi-wavefront at each antenna position, have a serious fault that the determined values at the interfered region are not accurate. In order to overcome this problem, we propose to estimate all quasi-wavefronts simultaneously from the received signal waveform at all antenna positions by treating the problem as an optimization of a cost function. |
