Target Orientation Detection Using UWB SAR by Implementing Polarimetry Technique

Abstract: In a recently started research project which took place at University of Gavle during the year 2015 an ultra-wideband (UWB) synthetic aperture radar (SAR) for non-destructing evaluation of walls was used to detect the metal target (pipe). The SAR used is designed by a small radar company in Gavle called Radarbolaget. This thesis is the aim to improve the detection capability of the SAR. The improvement is based on target (metal pipe) detection at different orientation angle by implementing polarimetry technique on SAR system. The SAR is then set to scan the target at four different polarizations and process the signals of repeated measurements with four different polarization of the transmitter and receiver antennas. The data from the target is then processed by the rotation matrix at different orientation angle using MATLAB to get new data matrix with their corresponding angles of rotation and process them by using SAIL algorithm to gives four 3D representation of the target. The target orientation can be simply identified by simply looking at the image with higher intensity.
