Abstract. The instrument function of two-element correlated radiometer with an unfilled aperture was calculated and constructed. Experimental investigations were carried out and antenna patterns were measured under different external conditions. Developed mathematical model has good coincidence with experimental results. The reasons influencing on the accuracy of two-element radiometer directional pattern measurement are discussed.
