METHOD AND DEVICE FOR DETERMINING ANGULAR ORIENTATION OF AIRCRAFTS Russian patent published in 2021 - IPC G01S5/02 G01S19/04 

FIELD: radio equipment.

SUBSTANCE: group of inventions relates to radio engineering and can be used to determine angular orientation of aircraft in space and on plane. In the method, determination of angular orientation of aircrafts is carried out using optimized spatial filtration when receiving signals of spacecrafts (SC) of global navigation satellite system (GNSS), which is based on a criterion of minimum output power. Method differs from known by calculation of reference phase differences Δϕ_ref. Values Δϕ_ref are determined from the difference of signals of two adaptive antenna arrays (AAA), wherein amplitude-phase shift introduced by each AAA is taken into account. To this end, the calculated phase differences take into account the values of the weight coefficients vector (WCV) of the corresponding AAA. Elimination of contradiction in implementation of adaptive antenna system related to simultaneous performance of spatial filtration of aircraft noise and angular orientation by replacement of M antenna elements on M AAA. Device for determining aircraft angular orientation, realizing the method, comprises M identical antennae from N antenna elements, M ≥ 3, N ≥ 2, a reference signal generation unit, a clock generator, S correlators, S analysis units, S + 1 switches, a correlator initial setting unit, S subtraction units, a memory unit, first and second calculators-generators, a decision unit, a control unit, a display unit, three input setting buses, a radio navigator, connected to each other in a certain manner.

EFFECT: technical result is high noise immunity to deliberate interference.
