Abstract
FIELD: radio engineering. SUBSTANCE: in compliance with first variant of method of direction finding and of direction finder realizing this variant radio signals of radio emission sources are received by omnidirectional antenna permanently connected to reference channel of double-channel receiver with common heterodyne and elements of antenna array connected in sequence to object channel of same receiver which are arranged in certain manner on surface of carrier in the form of N rings of same diameter incorporating m elements of antenna array in each ring and elements positioned in center of each ring. According to second variant of method of direction finding and of direction finder realizing this variant signals are received by elements of antenna array connected in sequence to object and reference channels of double-channel receiver with common heterodyne. Then measurement of signals in each object and reference channel is conducted in pairs on coinciding time intervals of signal spectra, amplitude-phase distributions on elements of antenna array and maximum of modulus of complex angular signal spectrum which orientation determines value of bearing are computed by mathematical formulas. EFFECT: diminished number of false bearings emerging as result of reception of electromagnetic waves reflected from surface of carrier. 4 cl, 5 dwg
