Fast and Accurate 3-D Imaging Algorithm with Linear Array Antennas for UWB Pulse Radars
Pulse radars with UWB signals are promising as a high-resolution imaging technique that can be used for the non-destructive measurement of surface details in industrial products such as antennas and aircraft. We have already proposed a fast 3-D imaging algorithm, SEABED, that utilizes a reversible transform between the time delay and the target boundary. However, data acquisition is time-consum...

متن کاملAn Accurate Imaging Algorithm with Scattered Waveform Estimation for UWB Pulse Radars
UWB pulse radars that offer target shape estimation are promising as imaging techniques for household or rescue robots. We have already proposed an efficient algorithm for a shape estimation method SEABED which is a fast algorithm based on a reversible transform. SEABED extracts quasi wavefronts from received signals with the filter that matches the transmitted waveform. However, the scattered ...
متن کاملA Robust and Fast Imaging Algorithm with an Envelope of Circles for UWB Pulse Radars
Sensor network systems with UWB signal have a great potential for a fast communication and a high-resolution imaging, which are required for house-hold robots or rescue robots. For this application, we have already proposed a fast imaging algorithm, SEABED based on a reversible transform between the received signals and the target shape[1]. However, the image with SEABED is instable in a noisy ...
متن کاملAn Experimental Study on a Fast and Accurate 3-d Imaging Algorithm for Uwb Pulse Radar Systems
A UWB pulse radar is promising as an environment measurement method for household robots and rescue robots. SEABED algorithm, one of the radar imaging algorithms, can estimate 3-D target shapes in a short time, which cannot be accomplished by conventional algorithms. However, the estimated image of SEABED algorithm has a systematic error even in a noiseless environment, which is caused by the d...
