Abstract(in English) Radar imaging techniques are important and applicable to many fields including rescue robots. Estimating target shapes using the data obtained by scanning an omni-directional antenna, is known as one of ill-posed inverse problems. We have already proposed an efficient algorithm of shape estimation based on a reversible transform BST (Boundary Scattering Transform) between a delay time and a target shape. We named the algorithm SEABED (Shape Estimation Algorithm based on BST and Extraction of Directly scattered waves). The algorithm has a remarkable performance in estimating target shapes. However, phase rotations of scattered waves caused by concave surfaces cause a great deal of degradation in estimating accuracies. We propose a phase compensation algorithm for high-resolution pulse radar systems in the present paper. The theory is presented first and numerical simulation results follow.
