摘要：

Large data volume owing to the long aperture of UWB SAR is one of the main difficulties in Real-Time UWB SAR imaging. Azimuth Pre-Processing (AzPP) can reduce the data volume, which make Real-Time imaging of UWB SAR become possible. In this paper, we analyze the AzPP characteristics in UWB SAR, and design the lowpass FIR filter under Chebyshev method. Then a parallel structure of AzPP based on TS201 is proposed. The computational cost and storage are also analyzed. Finally, the imaging result processed with the parallel flow is presented.
