TWI technology is an emerging research area used in urban warfare situation. Ultra wide band range signals has the capability of penetrating through the materials hence ultra wideband RADAR is suitable for this situation. To give the better representation of the scanned scene signal processing techniques are included on the raw data. In this paper, we used impulse RADAR for TWI and for the retrieval of B-scan signal back projection algorithm is used. Here we used a gain factor of 100 to increase the strength of echo. To reduce the clutter from B-scan signal SVD technique is used and the peak SNR is observed to be -3.30 dB Copyright © 2015 Inderscience Enterprises Ltd.
