Abstract
In order to meet the requirements of the verification of the key technologies of a spaceborne SAR radar,a high speed data acquisition system is designed and implemented.The system is composed of da-ta acquisition extension and grapher.Data acquisition extension adopts the COTS(commercial-off-the-shelf) devices and standard FMC(FPGA mezzanine card)architecture.The mother card is a general signal process-ing board with rich interfaces.The daughter card is a signal acquisition card which can be changed flexibly. The grapher uses the optical fiber communicating with the data acquisition extension.It owns a high-capacity DDR3 for high-speed data caching,and transfers data to computer with PCI-E bus.The system completed data acquisition in the flight test and the results verified the correctness and feasibility of the design scheme.关键词
