System to Detect Human Being Buried under the Rubble During Disaster: A Review

Electronics and Telecommunication Engineering

“Thousands of person killed as a cause of earthquake”.Such headlines of the newspaper come after the unavoidable casualty. Due to this, unlimited number of people die. It is nothing but the result of disasters such as snowfall, tunnel dropping and fall of landslides.In June 2013,the worst incident happened in Uttarakhand,when continuous rain came as effect of fall of landslides.The most important question arise that how to enable rescue teams to enter the area, where many bodies are buried under rubble during disaster. The microwave life detection system is developed to detect rescue of victims trapped under the rubble of collapsed building during the earthquake or other disasters. The proposed system uses microwave frequency signal which is able to detect movement of heart and respiratory system. The operation principle is based on Doppler frequency shift of the electromagnetic wave. These wave reflected back from the user which is present below the ground level. We decrease world death rate to greater extent by using such system.
