METHOD OF AMPLITUDE DIRECTION FINDING OF INTERFERING RADIO WAVES AND DEVICE REALIZING Russian patent published in 2020 - IPC G01S5/04 

FIELD: radio equipment.

SUBSTANCE: inventions relate to radio engineering and can be used in systems of detection and direction finding of two operating radio-frequency sources (RFS) simultaneously, which frequencies are in pass band of receiving channels. Method is based on generating beat envelopes U₁(t) and U₂(t) in the first and second receiving channels, respectively, by means of which the set of probable directions θ₁₁, θ₁₂ is calculated for the first and θ₂₁, θ₂₂ on the second RFS. To eliminate ambiguity of bearing taking, phase characteristics P₁(t) and P₂(t) of difference electromotive forces e_Δsy(t) and e_Δzv(t) are formed in the first and second receiving channels, respectively. Based on results of comparison of phase characteristics P₁(t) and P₂(t), true bearings θ₁ on the first RFS and θ₂ on the second RFS are selected. Method for amplitude direction finding of interfering radio waves is realized using an apparatus for amplitude direction finding of interfering radio waves, which is made in a certain manner.

EFFECT: reduction of time for evaluating bearings on the first and second RFS and high accuracy of amplitude direction finding of interfering radio radiations.
