METHOD OF MEASURING THE DIAGRAMS OF THE ANTENNA DIRECTION OF A RADIO RADIATION SOURCE, LOCATION OF WHICH IS UNKNOWN Russian patent published in 2018 - IPC G01R29/10 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna technology and radio engineering systems and can be used, for example, in radio-technical control systems. Measuring route is formed during the movement of FSC at a height H_beg by criterion ƒ_Dop=ƒ_mes.-ƒ_rad→0, where ƒ_Dop is the value of Doppler frequency; ƒ_mes. is the value of the radiation frequency of the IRI, measured at the FSC; ƒ_rad is a priori known frequency of IRI radiation, in the process of FSC moving along the measurement route simultaneously with the measurement of the signal parameter D_{antenna pattern} the length of the traversed path l_PP is fixed from the beginning of the movement along the measuring route with the frequency of data output by the FSC navigation system, at the moment of FSC returning to the starting point of the measurement route O_beg(B_beg,L_beg,H_beg) the formation of the route is completed, reception of the IRI signal and measurement of its parameter D_{antenna pattern}, final length of the traversed path L_PP is fixed, measurements are represented as a function of the traversed path length D_{antenna pattern} (I_PP), where l_PP ∈ [0,L_PP], IRI antenna pattern is measured in the form , where l_PP ∈ [0,L_PP].

EFFECT: technical result is the implementation of the measurement of IRI antenna pattern using FSC in the absence of information about its location.
