ABSTRACT
A new revolution microwave life detection system which is used to locate human beings buried under earthquake rubbles has been designed.
This system operating at a certain frequency can remotely detect the breathing and heartbeat signal the status of the person under the trap can be easily judged.
The entire process takes place within a few seconds. By advent of this system the world death rate may decrease to greater extent as large percentage of death occur due to earthquake.
PRINCIPLE OF OPERATION
Microwave beam of certain frequency is aimed at portion of rubbles.
It penetrates through the rubbles and detects the breathing and heart beat signals of human beings.
The reflected waves from the rubbles and humans are separated
The waves from the rubbles are filtered.
The time periods of received waves are used to calculate the distance of objects using affixed speed of microwaves and hence the human lives are saved.
