Problem statement. Direction finding of radio emission sources is expensive the computing procedure substantially defining speed of functioning of multichannel system of radio monitoring. In a case direction finding not only on an azimuth, but also on elevation, computing expenses increase several times as it is required to calculate two-dimensional direction finding a relief and to apply methods of multidimensional numerical optimization azimuth-elevation direction finding with conservation of efficiency factors of radio monitoring in multi-purpose conditions it is necessary to develop the specialised approach for time reduction on decrease in computing expenses.

Objective. To develop algorithm of identification of amplitude-phase portraits of radio signals in azimuth-elevation planes and specifications in time of a joint assessment of an azimuth and elevation of source.

Results. Unlike modern means direction finding signals in each supervision, the offered approach is based on formation of an amplitude-phase portrait of signals of sources of a radio emission and procedure of dynamic identification of portraits in time on the basis of an accessory to one source.

Practical significance. Realisation of the yielded algorithm in instrumentation of perspective multichannel systems of radio monitoring will allow to reduce considerably volume of a used computing resource, to raise speed and degree of intellectualization of system of the radio monitoring functioning in the conditions of complex multi-purpose electromagnetic conditions.
