Robots Use EM Waves to See Through Walls

Robots Use EM Waves to See Through Walls

Robots are by now well-established parts of the military electronics landscape, whether on the ground, in the air, or at sea. By combining ground robots with detection systems based on electromagnetic (EM) energy, they can also play quite effective roles in search and rescue, as well as surveillance and security applications. These see-through imaging systems, which are also known as “through-wall imaging,” can work with EM energy as popular as 2.4-GHz Wi-Fi signals and a pair of robots to perform the through-wall detection. Using Wi-Fi received signal strength indicator (RSSI) signals, one of the robots measures the received signal power of the signals transmitted by the other robot to perform imaging of objects through a wall. A trio of researchers developed both narrowband and ultrawideband (UWB) imaging approaches using commercial transceivers and antennas. The researc...
