It is getting harder to hide from US military
The U.S. Army is sending the troops a new generation of "see-through-the-wall" devices. The Eagle series of sensors use low power ultra-wideband radio waves to detect what is behind walls (except metal ones). These devices weigh 3.5-6 pounds (there are three versions) and all are handheld. The M model can detect motion, of people or animals who are up to six meters behind a 20cm concrete wall. The P model can see into the ground (3-4 meters down) and detect objects, as well as tunnels. The V model produces sharper images, but at shorter ranges. All these devices use rechargeable batteries that are good for about four hours. The sensors look like a game controller, and put the image on a small screen, as well as being able to wirelessly transmit the image to a laptop computer, which can use software to enhance the image. These non-radar sensors are popular with police and fire departments, as well as anyone who has to search behind walls, or under roads, for stuff that is broken.A similar piece fo equipment has been in use, but it was not as good as the new stuff. I think this has to be a product that the special forces will find useful in their raids on enemy compounds.
