Death of lots of people occurs as a cause of earthquake. Such news comes in newspaper after the unavoidable casualty. Because of this, unlimited numbers of people die. It occurs as a result of disasters such as tunnel dropping, snowfall and fall of landslides. The effect of fall of landslides occurs in June 2013, due to heavy rain came in Uttarakhand. Such worst incident happened in 2013, because of this, lost precious lives. When many people are buried under rubble during disaster, at that situation the most important question come in mind that how to enter the area using rescue teams .The microwave life detection system is developed to detect subject or object buried under the rubble of collapsed building during the earthquake or other disasters. The object or subject includes human being/ victims. The proposed motion detection system uses microwave frequency electromagnetic signal which is able to detect motion of moving object. This system decides whether the object is in motion or not. The Doppler frequency shift of the wave is the operational principle of motion detection system. The motion detection system uses microwave doppler radar sensor sense these waves reflected back from the object if object is in motion and present below the ground level. Once the motion is detect, then able to decide whether the object is human being or not. Then system using microwave test bench is used to decide whether the object is human being or not. Also, system operate using microwave test bench used to detect the breathing and heartbeat signals of subject. The matlab simulink model show heartbeat and breathing signal. By using all these system, able to decrease world death rate to greater extent.
