GONIOMETRIC-BASE METHOD OF RANGE MEASUREMENT Russian patent published in 2002 - IPC

FIELD: radio engineering. SUBSTANCE: invention is related specifically to systems determining range without use of reflection or secondary radiation and measuring range to spatially distributed radiation sources. Proposed method includes reception of radiation of radiation source with the help of two receivers placed at base distance one from another and fitted with narrow-beam antennas, measurement of angles of directions of reception of radiation of source by antennas A₁ and A₂ correspondingly with reference direction in which capacity perpendicular to line A₁A₂ is assumed and computation of range to radiation source by formula: R = d•cosϕ₂/sin(ϕ₂-ϕ₁), where R is distance from radiation source to antenna A₁; d is base distance between antennas; ϕ₁, ϕ₂ are angles of directions of reception of radiation of source by antennas A₁ and A₂ correspondingly with reference direction. EFFECT: increased accuracy of measurement of range. 3 dwg
