Abstract

In recent years, according to the bandwidth of SAR in X-band would be legally expanded up to 500 MHz in order to improve the resolution of SAR images, the bandwidth of SAR would be overlapped with that of the many ground-based radars in same band. This paper analyzes the interference effect to Spaceborne SAR by ground based radar operating in the Korea peninsula. The point target and SAR data is used to show interference effect based on mathematical modeling. The point target simulation is analyzed that sidelobe level of the point target increases as -40dB and the range resolution could be worse by narrowing IRW. The result based on SAR real data is shown to verify the interference effect from ground based radar.
