Interferometric radars are widely used for static and dynamic monitoring of large structures such as bridges, culverts, wind turbine towers, chimneys, masonry towers, stay cables, buildings, and monuments. Most of these radars operate in Ku-band (17 GHz). Nevertheless, a higher operative frequency could allow the design of smaller, lighter, and faster equipment. In this paper, a fast MIMO-GBSAR (Multiple-Input Multiple-Output Ground-Based Synthetic Aperture Radar) operating in W-band (77 GHz) has been proposed. The radar can complete a scan in less than 8 s. Furthermore, as its overall dimension is smaller than 230 mm, it can be easily fixed to the head of a camera tripod, which makes its deployment in the field very easy, even by a single operator. The performance of this radar was tested in a controlled environment and in a realistic case study.

用于桥接测试/监控的 W 波段 MIMO GB-SAR

干涉雷达广泛用于桥梁、涵洞、风力发电机塔、烟囱、砖石塔、斜拉索、建筑物和纪念碑等大型结构的静态和动态监测。大多数这些雷达工作在 Ku 波段 (17 GHz)。然而，更高的工作频率可以允许设计更小、更轻和更快的设备。在本文中，提出了一种在 W 波段 (77 GHz) 中运行的快速 MIMO-GBSAR（多输入多输出地基合成孔径雷达）。雷达可以在不到 8 秒的时间内完成一次扫描。此外，由于其整体尺寸小于 230 毫米，因此它可以轻松固定在相机三脚架的头部，这使得它在现场部署非常容易，即使由一个操作员也能做到。该雷达的性能在受控环境和实际案例研究中进行了测试。
