A hardware design of a data acquisition and storage system based on PCI and FPGA for the baseline measurement system of dual-antenna interferometric SAR is proposed and implemented, for fulfilling the high speed and real-time requirements. The system realizes high speed data transmission between PCI bus and CCD camera and Laser range finder. The system controls and buffers the data by FPGA and large amount SDRAM using multiple hard disk array for real-time storage. The performance test results show that the system has large data throughput, good real-time, and stable performance.
Key words： baseline measurements; FPGA; PCI bus; data acquisition; real-time data storing
