Variations of the direction-finding characteristics in the case of the direction finding of the source of a signal with unmatched polarization

A method for calculating the direction-finding characteristics for a radiation source with arbitrary polarization is proposed which is based on the representation of the complex pattern of the receiving antenna in the form of the product of the directivity pattern (in the case when the polarizations of the antenna and signal are matched) and the polarization matching function. The method is applied to an amplitude multipulse coordinator. An explanation is given for large errors previously observed in measuring the angular coordinates of a source of radiation with unmatched polarization.
