Abstract
A method to compensate for nonlinear distortions in correlation radiometer arising under the action of a powerful blocking interference at one of its inputs is proposed. The method is based on selecting the instantaneous interference power at the overloaded LNA input of the correlation radiometer and using it for the calculation and correction of the distortions involved. The article is concluded with the experimental estimates of the method.
