The unpremeditated radioelectronic conflict of spaced radio monitoring (RM) and interference facilities (IF) which operate within the electronic complex of radar ECM is discussed. The analysis of reduction in RM efficiency under unpremeditated noise interference (NI) conditions is suggested to perform on the basis of permissible decrease in range of radar radiation radio monitoring. The RM facility-s sensitivity of equivalent receiver is introduced in which the power of unpremeditated noise interference and the decimal logarithm of permissible decrease in range of radar radiation radio monitoring are taken into account. The quadratic equation of canonical form is deduced by change of variables. The root of the equation defines the analytical dependence of permissible distance between radio monitoring and interference facilities such that the requirements for decrease in range of radiating objects detection within admissible limits under NI conditions are fulfilled. Graphic dependences of permissible distance between a RM facility and an IF against their type technical data are plotted. The obtained results would be appropriate to use when solving important practical problems in justifying the requirements both for technical characteristics of spaced RM and interference facilities operating within the same complex and for their mutual arrangement.
