High resolution imaging with a holographic radar mounted on a robotic scanner

摘要

Ground penetrating radars operating at high frequency are currently used for subsurface investigation. The data are generally collected by manual scans and this is a time consuming process and it is also affected by errors in spatial positioning of the data. In this work, we present an innovative approach by devising a robotic scanner that is remote controlled. The robot scanner operates with a high resolution 3.6-4.0 GHz multi-frequency holographic radar antenna of RASCAN type. The paper describes the advantages of this new instrument in different applications fields (civil engineering, archaeology, land mine detection) with high resolution images of shallow objects and virtually zero set up time for the experiments.
