A Survey on Efficient Life Detection System Using Microwave Signal

Abstract

Thousands of persons killed as a reason behind earthquake. The on top of words is not the
headlines of the newspaper, however, such news come back once the disaster destroyed the
sector. The disaster within the big apple town at ‘World Trade Center’ claimed lives of quite
5000 individuals. It absolutely was aforementioned if survivors have been found and rescue
earlier the numbers of victims are lower. There is without stopping to the amount of lives lost
because the results of such disasters as landslides, folded tunnels and avalanches. The
microwave life detection system is developed for the search and rescue of victims at bay
underneath the dust of folded building throughout the earthquake or different disasters. The
projected system utilizes L-band frequency that is ready to notice metabolic process and
heart fluctuations. The operation principle relies on physicist frequency shift of the radiation
mirrored from the buried victim. The schematic diagram of microwave
Transmitting/Receiving (T/R) and litter cancellation scheme square measure enclosed during
this report. During this report varied components of a microwave life detection system like
antenna, directional mechanical device, and splitter has been mentioned. By advent of this
technique the planet death rate as a reason behind an earthquake might decrease to larger
extent.
