The analysis of microwave radiometric measurements data is provided in the L range, executed from June to August 2011 by the radiometric PK-21-8 complex mounted onboard of RS ISS. Decade cards of radiation of the earth surface are constructed. The analysis of data showed that in certain regions of a land and oceans were almost constantly observed RFI signals which were in most cases caused by operation of land radars and other sending devices. Results of measurements from ISS are compared to results obtained by means of foreign satellites in the same range. Factors of a natural origin, such as the radiation of the Sun, reflected from a surface of the water, the background radiation of the sky and instrument impacts are considered.
