Identification of Humans in a Disaster using Radio Frequency Technique

Disasters are unpredictable phenomena that occur in different periods, cause damage and sometimes loss of life. There are various types of disasters that include flooding, drought, wildfires, earthquakes, and building collapse. Some of them happen naturally while others are caused due to human ignorance and affect the infrastructure. This research focuses on identification of human beings trapped in rubble of a collapsed building to increase the chance of survival using the microwave technique. The proposed methodology is used to estimate the digging in the correct direction that is difficult to discover human lives. Radio frequency waves are transmitted that pass through the rubble and detect humans by the reflected signal. The change due to transmitting and receiving signals is observed via an antenna that triggers an alarm to indicate the human presence. This technique is implemented using a robot that can travel difficult to access places. The system has been tested at small scale with satisfactory results.
