Abstract: The influence of external disturbances on the sensitivity and dynamic range of the microwave radiothermograph is considered. The results of an experimental study of the interference situation in the range up to 3 GHz are presented. The diagram of the spectral density of interference adjacent to radio astronomy windows is analyzed. The features of real observed disturbances are investigated. The classification of possible disturbances according to their characteristics is given. Algorithms for discrimination of various types of interference are considered. The sensitivity and dynamic range of the microwave radiometer are evaluated using the pulse noise suppression algorithm.
Keywords: microwave radiothermography, pulse interference, narrowband interference, radiometer sensitivity, dynamic range
