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
radiometer, instrument function, millimeter range.
