摘要：

This paper describes characteristics of the L band radio interferences appeared in the JERS-1 SAR images, which were acquired world widely during six years and a half. It also describes a filtering method that mitigates the radio interference. Tins filtering method replaces the interfered component of SAR raw data by zero padding from the statistical power spectrum analysis. The corrected SAR raw data is well correlated with the SAR imaging reference signal and the Output image is shown to be useful.
