| 總結: | Synthetic Aperture Radar (SAR) is a unique imaging radar system that is capable of obtaining high resolution image by using signal processing techniques while operating in all-weather with the absence of light source. This capability has been widely used in observing the properties of the Earth’s for the past few decades. The potential of SAR in a wide range of applications has led to new challenges in digital SAR processor design. In particular, on board storage of SAR raw data is often not practical for real-time applications. Furthermore, the design of digital SAR processor is always restricted by the available space of the carrier system, data transfer rate, payload capacity and the on board power supplies. As reported in the literature, although customised hardware solutions could offer the desired performance but it is not feasible for low volume production. This research work aims to design and develop an efficient digital SAR processor by using Field Programmable Gate Array (FPGA) with the consideration of hardware resources, power consumption, processing speed and precision. |
