Super-resolution Imaging Technique Using Multiple ScatteringEnvironment for Collision Avoidance Robot Sensor

UWB雷达系统具有足够的距离分辨率，适用于室内传感系统，作为近场传感器在多尘、强背光等恶劣光学环境下工作，具有广阔的应用前景。本项目致力于将原有的RPM(距离点偏移)方法扩展到各种类型的观测情况。此外，通过利用多次散射信号的特点，我们开发了一种创新的成像方法，克服了传统方法所获得的空间分辨率或精度。电磁分析的数值模拟结果表明，我们开发的技术提供了波长精度为1/100量级的极高精度的三维成像，并显著扩大了目标边界的可重构区域。

UWB radar system holds sufficient range resolution to be suitable for indoor sensing system, and is promising as near field sensor being active in optically harsh environment, such as dusty air or strong backlight. This project focuses on the extension of the original RPM (Range Point Migration) method to various types of observation situations. In addition, by exploiting the feature of the multiple scattering signals, we have developed an innovative imaging method overcoming the spatial resolution or accuracy obtained in the conventional methods. Results from numerical simulation using electro-magnetic analysis offers that our developed techniques provides an extremely accurate 3-dimensional imaging at the order of 1/100 wavelength accuracy, and remarkably expands the reconstructible region of the target boundary.
