Target estimation methods with UWB pulse signals are promising as imaging techniques for interior robots.
We have already proposed an efficent algorizhm of shape estimation named SEABED, which is based on a reversible transform between the time delay and the target shape.
In this method, we take a quasi wave front from a received signal with the matched filter of transmitted waveform in order to estimate a target shape.
However, a scattered waveform is in general different from the transmitted waveform depending on the shape of the target surface.
This difference causes estimation errors in SEABED method.
In this report, we propose a high-resolution algorithm of polygonal-target shape estimation based on the scattered waveform estimation, and evaluate the method by numerical simulations and experiments. |
