2. INTRODUCTION
 THROUGH THE WALL HUMAN DETECTION IS OF INTEREST IN
MILITARY,DISASTER MANAGEMENT AND RESCUE OPERATIONS.
 THE PROJECT AIMS TO CONDUCT AN EXPERIMENTAL STUDY ON THROUGH THE
WALL HUMAN DETECTION USING USRP AS A TOOL.

3. KEY IDEA

USRP

4. PROGRESS OF THE PROJECT
 USRP – THE UNIVERSAL SOFTWARE DEFINED RADIO PERIPHERAL, WAS TAKEN AS THE TOOL TO
TRANSMIT AND RECEIVE SIGNALS.
 USRP 2932 IS USED , WHICH CAN TRANSMIT AND RECEIVE SIGNALS OF THE RANGE 400 MHz
TO 4.4GHz
 LAB VIEW IS THE INTERFACING SOFTWARE SINCE IT WAS COMPATABLE WITH USRP

5. CONT…
 FOR FURTHER SIGNAL PROCESSING MATLAB IS USED
 WE HAVE SELECTED TO TRANSMIT A PULSE OF 1GHZ FREQUENCY
 THE TRANSMITTER AND RECIEVER PART OF THE USRP WAS DESIGNED AND
IMPLEMENTED USING LABVIEW.

6. CONT…
IN THE FIRST PHASE OF THE PROJECT,
 IMPLEMENTED THE TRANSMISSION AND RECEPTION OF THE SINE WAVE OF
1GHz.
 THE REFLECTED SIGNAL FROM A HUMAN TARGET WAS ALSO OBTAINED.
 DATA SETS FOR THE HUMAN DETECTION WITHOUT OBSTACLE WAS TAKEN
AND THE MAGNITUDE RESPONSE OF THE RECEIVED SIGNAL WHICH INDICATES
THE PERIODICITY OF HEART BEAT WAS PLOTTED.

9. FUTURE WORKS
 CLEAR ESTIMATE AND DATA SETS FOR THE PRESENCE AND ABSENCE OF
HUMAN BEING THROUGH THE WALL WILL BE PLOTTED.
 TO DEVELOP PLOTS WHICH CAN CLEARLY INDICATE HUMANS AND WHICH
CAN BE FURTHER SUBJECTED TO FUTURE WORKS TO DEVELOP A SYSTEM TO
DETECT HUMAN TARGETS FROM UNDER THE BUILDING RUBBLES.
 IMPLEMENT CLUTTER REDUCTION TECHNIQUES

10. CLUTTER REMOVAL TECHNIQUES
 Singular Value Decomposition (SVD)
 Factor Analysis
 Principal Component Analysis (PCA)
 Independent Component Analysis (ICA)
