ACKNOWLEDGEMENT
We would like to express our heart full gratitude to all those who have helped to bring
our project to a successful completion. This seminar is the sum total of the imprint of many
persons who have contributed their valuable time and energy.
I take this occasion to express our sincere gratitude to all those who have helped us in
this endeavor especially Dr. K.V Sundaresan, respected Principal of FEDERAL
INSTITUTE OF SCIENCE AND TECHNOLOGY (FISAT), Mrs. Mini P.R. (Head of
Department, ECE), Mrs. Shamseena M A (Lecturer, ECE Department) & Ms. Shameem S
(Lecturer ECE Department) whose guidance has helped me to make this seminar a success.
Above all we thank God, for this mercy and blessings which helped us for the
successful completion of this seminar. Last, but not the least we wish to express our heartfelt
thanks to all of our friends for their goodwill and constructive ideas.
ABSTRACT
A new sensitive microwave life-detection system which can be used to locate human
subjects buried under earthquake rubble or hidden behind various barriers has been
constructed. This system operating at 1150 MHz or 450 MHz can detect the breathing
and heartbeat signals of human subjects through an earthquake rubble or a construction
barrier of about 10-ft thickness.
The basic physical principle for the operation of a microwave life-detection system is rather
simple. When a microwave beam of appropriate frequency (L or S band) is aimed at a pile
of earth- quake rubble covering a human subject or illuminated through a barrier
obstructing a human subject, the microwave beam can penetrate the rubble or the barrier to
reach the human subject. When the human subject is illuminated by a microwave beam, the
reflected wave from the human subject will be modulated by the subject’s body movements,
which include the breathing and the heartbeat. If the clutter consisting of the reflected wave
from sta- tionary background can be completely eliminated and the reflected wave from the
human subject’s body is properly modulated, the breathing and heartbeat signals of the
subject can be extracted. Thus, a human subject buried under earthquake rubble or hidden
behind barriers can be located.
This system has been tested extensively in a simulated earth- quake rubble in the
laboratory and also in a field test using realistic earthquake rubble conducted by a Federal
Emergency Manage- ment Agency (FEMA) Task Force
