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
