DOPPLER PHASE-METER OF MULTIFREQUENCY SIGNALS Russian patent published in 2001 - IPC

FIELD: measurement technology, measurement of radial velocity of object in multifrequency radars of simultaneous radiation, radiolocation and navigation systems for unambiguous determination of Doppler velocity. SUBSTANCE: Doppler phase-meter of multifrequency signals has two frequency channels which process initial readings on basis of units of delay, complex ganging, complex multiplication, averaging and modulus computation, circuit computing evaluation of Doppler velocity on basis of units computing phase, correction of measurement limits connected in series and of additional multiplier and two circuits of integration of frequency channels on basis of additional adder and additional complex multiplier together with unit of complex ganging whose usage makes it feasible to raise detection efficiency and to ensure required range of unambiguously measured Doppler velocities which is technical result of invention. EFFECT: raised detection efficiency and ensured range of unambiguously measured Doppler velocities. 10 dwg
