Introduction
Principle of operationMicrowave beam of certain frequency [L
(or) S band(1150Mhz (or) UHF band(450MHz] is aimed at a portion of rubble.
Microwave beam detects the person.Heartbeat (0.2 to 3Hz).Reflected wave.Iteration process.Process is of few seconds.
Major componetsFour major componets
A microwave circuit
Clutter cancellation system.
A dual antenna system.
Display
Phase locked oscillatorThe PLO generates stable electromagnetic
wave 0f 1150 MHz with power 400mWAntenna system:The dual antenna system has two antennas,
Clutter cancellation system
ConclusionNew life detection system using microwave
radiation for identifying human beings within the short time.
