Study Of High Speed Data Recording Techniques And System Realization In Airborne UWB SAR

High Speed Data Recording System is one of the key techniques in UWB SAR. It is applied to record the high speed, large capacity data stream, and it is important for real time signal processing.The paper has realized a set of High Speed Data Recording System using system integration techniques based on PCI Local Bus.I Using multithread programming technique meets on the request for real timeof High Speed Data Recording System in UWB SAR. A series of High Speed Data Recording software has completed based on Windows 2000. It is practical and reliable.II Secondly, the paper puts forward the method of synchronization test of HighSpeed Data Acquisition System and performance test of Data Storage System , presents the test results.III In the end, analyzes the effect of amplitude and phase errors of I and Qchannels on the imaging, puts forward the measuring and correcting project for it.This System has been used in the experimention of UAV UWB SAR in 2003 year. It works very well.
