The article considers the approach to the evaluation of radar efficiency under the influence of cross-polarization interference combined with target. The efficiency of angular coordinates measurement by monopulse radar with the phase method of total-difference pattern (TDP) formation under the influence of cross-polarization interference combined with the target is evaluated. The efficiency estimation is carried out by simulation modeling method. It is shown that the powerful interference on orthogonal polarization, combined with the target reduces errors of measuring the angular coordinates of the target when receiving a reflected signal and an interfering signal modulated in polarization.
