利用超宽带脉冲雷达进行目标形状估计是一种很有前途的家用机器人成像技术。我们已经提出了一种快速成像算法，SEABED，这是基于接收信号和目标形状之间的可逆变换BST（边界散射变换）。然而，通过SEABED获得的目标图像在噪声环境中恶化，因为它利用了接收数据的导数。在本文中，我们提出了一个强大的成像方法与圆的包络。我们澄清，通过数值模拟，所提出的方法可以实现一个水平的鲁棒性和快速成像，不能实现的原始SEABED。
Target shape estimation with UWB pulse radars is a promising imaging technique for household robots. We have already proposed a fast imaging algorithm, SEABED, that is based on a reversible transform BST (Boundary Scattering Transform) between the received signals and the target shape. However, the target image obtained by SEABED deteriorates in a noisy environment because it utilizes a derivative of received data. In this paper, we propose a robust imaging method with an envelope of circles. We clarify by numerical simulation that the proposed method can realize a level of robust and fast imaging that cannot be achieved by the original SEABED.
