Annotation: A new method of radiometer sensitivity enhancement is described. The effect is achieved by simplifying of radiometers input microwave part. Simplifying process is used only for differential type of radiometers. All scientific results are shown at particular case of differential type radiometers – null type radiometers. The calculated efficiency is shown for on-board null radiometer used in remote sensing.

Keywords: null radiometers, method of differential measurement, microwave radiometry, passive microwave devices
