Micrometric deformation imaging at W-Band with GBSAR

Abstract

The paper presents the experimental evaluation of 94 GHz CW-FM Radar that can be configured as a Ground Based SAR (Synthetic Aperture Radar) for high resolution imaging and deformation control. This system has been designed to obtain and analyze data of deformations on different types of bodies, being able to detect range changes of the order of micrometers. After indoor testing and validation measurements, several experimental results obtained in different scenarios are presented. Finally the possibility of using the system for remote contact-less patient monitoring is analyzed.
