本文报道了近距离雷达系统的最新进展及其在木结构建筑无损检测中的应用。我们开发了一个雷达系统，有32个线性对准的天线元件，工作在10-20GHz。这个系统可以在墙上获得相当密集的数据。然后基于稀疏阵列的思想，讨论了二维阵列系统的可能性。我们证明了8-ch阵列雷达系统可以在没有运动的情况下可视化雷达扫描的三维结构。然后，我们证明了极化信息可以成像非常小的建筑物结构，这是受雷达分辨率的限制。
We report our recent development in near rage radar systems and their applications to Non Destructive Inspection (NDI) for wooden buildings. We developed a radar system having 32 linearly aligned antenna elements operating at 10-20GHz. This system can acquire quite dense data on a wall. Then we discuss the possibility of 2-dimentional array system, based on the idea of sparse array. We demonstrated that the 8-ch array radar system can visualize the 3-dimentional structure without movement for radar scanning. Then we demonstrate that polarimetric information can image very small structure of buildings, which is under the limitation of radar resolution.
