U radu je prikazan uticaj metode ometanja "Cross eye" na uspešno vođenje rakete monoimpulsnom radarskom glavom za samonavođenje. Analiza dobijenih rezultata pokazala je: da se maksimalna greška određivanja položaja cilja postiže kada ometači emituju koherentne signale čija je fazna razlika 180°, da je greška veća što je međusobno rastojanje između antena ometača veće, da je, suprotno očekivanju, efikasnost ometanja veća što je rastojanje između ometača i rakete koja se ometa manje. / This article shows the effect of the "Cross eye" jamming method on successful guidance of monopulse homing missiles. The analysis of the results has shown that the maximal tracking error is made if the jamming signals are coherent and out of phase, that a larger distance between jamming antennas causes a greater error, and that, opposite to expectations, a smaller distance between the jammer and the missile results in better jamming effects.
