Abstract
We propose a method allowing one to improve the accuracy of retrieving the temperature distribution over the object surface by taking into account the influence of the antenna patterns of a multichannel radiometer on the measurement results at the nodal points. The accuracy improvement that is equivalent to an increase in the number of the measuring channels of the system from 9 to 16 is achieved. The positive effect is enhanced with increasing antenna-pattern overlapping degree.
