Taking over from the previous batch of Final Year Project students, whom had worked with the radar team from Temasek Lab (TL) @ NTU. The design of a full Polarimetric (POL) Synthetic Aperture Radar (SAR) system was fully developed by the previous team. However, the design has yet to be implemented into an actual SAR. Hence, this paper will include the details and the steps to implement the design into an actual SAR and the various testing and commissioning done to the system. In addition, several improvements were also made to the previous system such as the shifting of the 15GHz centre frequency of the system to the currently accepted 16GHz which was a requirement by IDA. Due to the need for the SAR system to be portable, the total power consumption of the system had to be satisfied in order for the system to last throughout the entire experimental trials. This paper will also introduce the method of selecting the correct type of voltage regulator boards and lithium polymer battery to sustain the entire system. This paper will also include a section on how actual experimental data was obtained from the SAR system via the conducting of an outdoor experimental trial and the various data processing method done via MATLAB for the combination of the various polarization images obtained from the trial to a single pseudo colour image. Further discussion on how to calibrate the individual polarized images prior to combination to obtain a clean final image will also be included.
