An embedded control and monitor system for SAR using SOPC technology

In the future, Synthetic Aperture Radar (SAR) requires enhanced capabilities, such as all-weather and better resolving power, more widely used in sciences, etc. New system to improve the control and monitor capability is desired by the development of the carrying-platform and SAR itself. A fast and small control and monitor system has been developed and tested. It employs SOPC (System On Programmable Chip) technology to satisfy the requirements of more advanced vehicle behavior in a small package, high-performance computing, and low power consumption, etc. The system presented in this paper is designed of Xilinx VirtexII p20 chip; a 1553B chip, an A/D chip has a SPI interface, etc. The project use PowerPC 405 embedded in V2P chip as a control computer to save PCB space, reduce total power consumption and enhance the computing capability of the system. This paper focuses on the design aspects of the hardware and the software of the system. Some experiments´ results are given in this paper.
