Global Radio Frequency Interference of L-Band SAR Data

SAR data acquisition is increasingly challenged by the overcrowded radio frequency bands, a phenomenon known as Radio Frequency Interference (RFI), particularly at L-band. We implement a robust algorithm to measure global RFI in SAR data. We process the entire L-band SAR data archive acquired by the JAXA JERS-1 and ALOS-1 satellites to provide a global view of RFI in L-band SAR data. The RFI detection results are saved in a predefined format. These RFI products can provide guidance on SAR data applications and prepare us for the upcoming L-band era.
