The microwave life detection system is developed for the search and rescue of victims trapped under the rubble of collapsed building during the earthquake or other disasters. The proposed system utilizes L-band frequency which is able to detect respiratory and heart fluctuations. The operation principle is based on Doppler frequency shift of the electromag-netic wave reflected from the buried victim. The schematic diagram of microwave Trans-mitting/Receiving (T/R) and clutter cancellation subsystem are included in this report. In this report various parts of a microwave life detection system s...
The microwave life detection system is developed for the search and rescue of victims trapped under the rubble of collapsed building during the earthquake or other disasters. The proposed system utilizes L-band frequency which is able to detect respiratory and heart fluctuations. The operation principle is based on Doppler frequency shift of the electromag-netic wave reflected from the buried victim. The schematic diagram of microwave Trans-mitting/Receiving (T/R) and clutter cancellation subsystem are included in this report. In this report various parts of a microwave life detection system such as antenna, directional coupler, and splitter has been discussed. By advent of this system the world death rate as a cause of an earthquake may decrease to greater extent.
