HELICOPTER PASSIVE ALL-ROUND DIRECTION FINDER |
摘要 |
FIELD: radio direction-finding, applicable for determination of direction to electromagnetic radiation. ^ SUBSTANCE: the direction finder uses a large-aperture receiving active phased array representing a set of modules positioned on the surface of the helicopter rotor. All-round view of the space is provided due to rotation of the helicopter rotor. Phasing in the antenna is realized by means of auxiliary radiation that is formed by the primary feed of the helicopter. The controlled phase in each module is set practically instantaneously irrespective of the other modules of the array, for provision of independent phasing of each radiator use is made of the information contained in the auxiliary radiation. ^ EFFECT: provided determination of the direction to the radiating objects and all-round view of the space at a high rate. ^ 1 dwg
