Abstract :
For single dish radiotelescopes the proposed approach for the mitigation of the radio frequency interference (RFI) problem calls for the illumination of the reflector antenna by a monopulse feed and the Dicke-switching of the input of its radiometer between the sum and difference ports. The same approach can be used for array-based radiotelescopes
