Detection: antipersonnel landmines

Detecting and locating antipersonnel landmines is a critically important mission in certain parts of the world. To that effect, we provide a UAS-based radar system that is both safe and efficient. First, the system produces high-resolution images of the area. Then, the images are processed through SAR (synthetic opening techniques) to further improve their accuracy and locate any buried landmines present at the site.

Technology

Technology: active sensing

For the purposes of detecting buried objects in general, and landmines in particular, we employ a UAS payload involving radar technology. The system irradiates microwaves that are reflected in a certain way when they penetrate the soil and find unexpected surfaces. This reflection data is then utilized to reconstruct a radar image with SAR and other techniques. In the case of landmines, the system operates at a depth of 10 cm.

Application cases

Buried IED detection

You can see one specific setup for measurement: 9 cm metallic disk on top of a plastic briefcase and near a 9,5 cm radius metallic box buried in a hole of 8 cm depth covered with soil. After several techniques of post-processing, we obtain several slices of the 3D SAR reconstructed image. It can be seen clearly two objects, the surface one, and the buried object.
