Error Evaluation of BAQ Algorithm for Calibration Data of Spaceborne SAR

摘要：

BAQ is the efficient algorithm for SAR echoes data compression that has the Gauss distribution. Internal calibration is the important system resource, which is to calibrate the system gain change before and after the imaging and also provide more accurate reference function for the range compression. But the echoes are different from calibration data. This paper discussed whether the error brought by BAQ compression algorithm could be accepted by this system. Both the theoretical simulation and the experimental results indicate that the internal calibration data only can be directly transmitted but not compressed, which has the important reference to engineering design.
