Through-the-wall imaging radar experiments based on 8-element vivaldi radar sensor

In this work, we present the experimental results and the formed radar images of Through-the-Wall Imaging Radar (TWIR) experiments that were conducted by our recently developed radar sensor. Experiments towards to detection and imaging of both the stationary and the moving targets were conducted. A back-projection type focusing algorithm was applied to focus the raw radar images. The resultant measured TWIR images with good resolution features in both depth and cross-range domain have demonstrated the notable performance of our radar sensor.
