A Review of Research of Life Detecting Radar

Public safety emergency rescue can now detect the characteristic signals of a living body (e.g. movement, breathing, heartbeat, etc.). This area of research uses life-detecting radars to identify the bodys type, quantity, direction, distance, gestures, and physiological characteristics. Life-detecting radars (LDRs) emit electromagnetic waves that can pass through walls or other covered media and probe for human life. This technology can be widely applied for search and rescue attempts in fires, landslides, mudslides, earthquakes, and other disasters. It can also be used to monitor personnels location in terrorism or hostage rescue activities, search for wounded soldiers on the battlefield, and lock enemy snipers in urban warfare and other environments.
