When facing irresistible natural disasters such as earthquakes and debris flows, accurately locating rescue targets within the crucial golden 72 - hour period becomes the key to racing against the clock and contending with death. At this time, life detectors become an indispensable and powerful assistant for rescue workers. Life detectors are a type of equipment that uses high - tech means to detect the signs of living life, and they are widely used in many fields such as disaster rescue, medical monitoring, and security inspection. It mainly confirms the presence of life by capturing specific signals emitted by the human body, such as body temperature, heartbeat, breathing, and electromagnetic waves. These devices are equipped with highly sensitive sensors that can accurately capture these weak signals, analyze and process them, so as to determine the specific location and physical condition of the trapped people.
The Life Detection Radar System, as an advanced life - detection device that combines radar technology and biomedical engineering technology, has a higher level of intelligence compared to acoustic detectors. In a ruin environment, it can accurately lock the position of people. Even if there are obstacles such as concrete walls, steel doors, and trees, in an open space, its detection range can reach up to 500 meters at the farthest. However, when encountering obstacles, the detection range will be shortened.
The working principle of the Life Detection Radar System is mainly based on the reflection characteristics of electromagnetic waves. When survivors move within a certain range, their limb movements or cardiopulmonary respiration will generate a time - domain Doppler effect on the radar echo. By monitoring various subtle displacements caused by human life activities and extracting relevant information such as breathing and heartbeat from them, it can be judged whether there are living beings.
At disaster scenes such as earthquakes, building collapses, debris flows, and avalanches, fire special service personnel or rescue teams do not need to enter dangerous areas. With the help of the Life Detection Radar System, they can detect the trapped within just 2.3 minutes. The signals collected by the device are processed and then sent to a personal digital assistant (PDA) via wireless transmission. There are hundreds of sets of dynamic data signals of the human chest during breathing pre - stored in the PDA. After receiving the signals, it will filter out the clutter and compare the waveforms, and then directly give a clear indication of whether there are signs of life. This function greatly simplifies the on - site search work of rescue workers.
