AIM OF THIS PAPER
Thousands of persons killed as a cause of earthquake
As a responsible engineer we have to save the human life.
We have proposed a new microwave live detection system to locate human beings.
PRINCIPLE OF OPERATION
Penetration of microwave beam through rubble surface
The reflected wave from the person s body will be modulated
These modulated signals are processed by controller and the location is determined
WORKING FREQUENCY
They are two categories depending on the type and nature of the collapsed building.
L or S band frequency say 1150 MHz
UHF band frequency say 450 MHz
MAJOR COMPONENTS
The microwave life detection system has four major components.
They are
A microwave circuit
Clutter cancellation system
Microcontroller
A dual antenna system
