Through-Wall Detection and Imaging of a Vibrating Target Using Synthetic Aperture Radar

What is it about?

The ability to image through mediums is of great interest to both civilian and defense sectors. Synthetic aperture radar (SAR) provides one such technique to achieve this. The project focused on the detection and imaging of running machinery within buildings and how this can be modeled through simulation and then validated within a controlled laboratory environment.

Why is it important?

In SAR imaging it is well known that a vibrating target will produce distinctive artefact's (known as paired echoes) within the image. Until now little had been done in investigating the effects on these specific targets and their artefact's when imaged through-a-wall. The outcome was an enhanced prediction capability for modeling SAR collections of vibrating targets with and without intervening walls. Alongside the developed software tools and laboratory techniques which will allow for further investigation of through-wall SAR phenomena and artefact's.
