Bin Huang · Telecommunication Engineering · 2011
In order to record SAR(Synthetic Aperture Radar) raw echo data,a method with SSD(Solid State Disk) on embedded Linux is provided in this paper.Linux drivers are used to manage the SAS(Serial Attached SCSI) controller and the data is stored in SSD with high-speed.The speed of data storage can achieve 200 Mbyte/s in experiment.The factors influencing storage speed are analysed.The test result shows that the design can satisfy the requirements of high-speed data storage.
