Millimeter waves Radar: A way to see through the airplane covering?

The usability of Ultra Wide Band terahertz radar technique for inspection and imaging of objects of interest for the aeronautics industry is under investigation in this paper. Frequency-modulated continuous-wave (FMCW) radar principle and systems will be detailed along with its benefits and limitations depending on the architecture and characteristics of the system as well as the materials under inspection. Promising results and advances in the airplane covering see-through problematic are also demonstrated through measurements that have been performed with our imaging systems, demonstrating the suitability of FMCW radars as a new tool for Non Destructive Testing (NDT) applications for the aeronautics industry.
