FIELD: radiolocation, radio navigation. SUBSTANCE: invention is targeted on expansion of functional capabilities of direction finder when finding direction to pulse signals (determination of angle of orientation of polarization diagram of found signals jointly with determination of angular coordinate of radiation source). Direction has first A, second Aand third antenna Aof right polarization circle, antennas of left polarization circle, polarization circle, first 1, second 2 and third 3 receivers, first 4 and second 5 heterodynes, first 6, second 7 and third 8 mixers, first 9, second 10 and third 11 intermediate frequency amplifiers, mixer 12 of reference beats, first 13 and second 14 beat mixers, first 15 and second 16 phase-meters. To output of receiver 1 (2, 3) there are connected in series mixer 6 (7, 8) which second input is coupled to output of heterodyne 4 (5), intermediate frequency amplifier 9 (10, 11). Outputs of intermediate frequency amplifiers 9 and 10 are connected to first and second inputs of first beat mixer 13 and outputs of intermediate frequency amplifiers 9 and 11 are connected to first and second inputs of second beat mixer 14. Outputs of first 4 and second 5 heterodynes are linked to first and second inputs of mixer 12 of reference beats. Output of first beat mixer 13 is connected to first inputs of first 15 and second 16 phase-meters. Output of mixer 12 of reference beats is second input of first phase-meter 15 and output of second beat mixer 14 is second input of second phase-meter 16. EFFECT: expanded functional capabilities. 1 dwg |
