The big congestion of a radio-frequency spectrum, in particular short-wave and ultrashort-wave its sites, is a principal cause of decrease in dynamic efficiency of functioning of prospecting equipment. The given factor directly influences decrease in values of fighting indicators of the systems using in interests of the functioning the prospecting information that is caused by high dynamism of conducting operations and, as consequence, small time of its operative value. One of directions of maintenance of the set degree of operative efficiency of functioning of systems of a fixing is rejection an entrance stream of radio emissions to a spatial sign - accessories of a priori set area of search. According to what, in article the way of definition of co-ordinates of sources of the radio emission, based on a triangulable method the site definition, providing rejection an entrance stream of contacts at the expense of correlation processing of results of supervision is offered. The being of a way of a fixing consists in realization synchronous on space and time пеленгования sources of radiation with the subsequent correlation processing of a stream of signals from each of direction finders, in interests of revealing of signals of those sources which co-ordinates belong to a priori set «looked through» area of space. Existential synchronization is realized by simultaneous formation of diagrammes of an orientation of the direction finders which direction of a maximum are focused on the geometrical centre of a looked through element of area of search. The analysis of influence of a parity of geometry of an element of the permission and area of crossing of diagrammes of orientations of aerials on probability of correct reference of a source of radiation to a looked through element of the permission, has shown that without dependence from a relative positioning of direction finders and search area the most expedient geometry of an element of the permission - a square.
