    Using an Agilent E5071B Vector Network Analyzer and Rotating Platform
    (2013) Grootboom, Lanche Linden; Wilkinson, Andrew John
    Ultra-Wideband (UWB) technology has become very famous amongst the radar imaging community. This system is well suited for tomographic imaging as it offers high special resolution and a low probability of detection. Some of the UWB applications include ground penetrating radar, medical imaging and some military applications. In this thesis an UWB radar imaging system has been designed and implemented using an Agilent E5071B Vector Network Analyzer and a rotating pedestal. The two ports of the device are used as a transmitter and receiver, measuring the frequency domain data of the scene in front of the antennas at each angular position as the rotating pedestal rotates in front of the antennas. This data is then put through a time domain back-projection algorithm which reconstructs an image of the scene. This is done in 2D space and then later extended to 3D space.
