| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Synthetic Aperture Radar is rapidly becoming a popular choice for aerial imaging due to the fact that it does not require any form of lighting and can operate in adverse weather conditions. We propose the design of a software based approach to a digital Synthetic Aperture Radar (SAR) processor. We also propose a system where the digital signals are fed to a computer and can be processed in real-time. This processor system allows for a modular approach to the research and development of newer algorithms SAR systems. We attempt to mitigate the specific requirements of processing a radar signal in real-time, direct from the analog return by applying some changes to typical signal flow. A typical digital SAR system requires the combination of a complex system comprising of an analog system, an analog to digital interface, storage and a processor system. This system is usually a form hard-coded for of digital logic designed to meet strict timing requirements. The recent advent of high speed ADCs and DAC as well as the recent performance increase in Ethernet technologies allow for a system that is capable of transferring data through an industrial standard and common form of connection. Our current demands of a digital SAR system also gives us some headroom in term of processing power enabling us to perform relatively fast processing of signals using a typical PC. The taxation of the program complexity is also reduced by using various forms of hardware processing such as GPGPU processing. Existing algorithms have been modified to run GPGPU and performance increases have been obtained. This system should allow for faster development of SAR systems as the input and output signals can be defined via software thus reducing the need for major reengineering. | |
