Definitions

  • the present invention relates to a multi-channel rotary joint for electromagnetic detection equipment.
  • Electromagnetic detection equipment generally known as Radar and which include so-called secondary radars generally include an antenna which rotates in a bearing and also sometimes in elevation.
  • a rotary joint which is placed in the feed path of the antenna.
  • the invention therefore relates to a rotary joint, that is to say in fact to a device intended to transmit high frequency energy between two circuits, in general without mechanical contact and in rotation with respect to one another. the other.
  • a primary radar associated with a secondary radar whose antenna is mounted on the antenna of the primary radar where it is necessary to provide for the main or primary radar, a transmit channel, a sum receive channel and at least a reception channel difference and for the secondary radar, a interrogation channel, possibly a control channel for suppressing the secondary lobes, a sum response channel, a channel suppressing the secondary lobes and a difference channel for establishing the crevice.
  • the object of the invention is then to define a multi-way rotary joint of annular type which is free from the drawbacks which have not been reported.
  • a rotary-multi-path joint comprises, arranged around the axial main track a number of annular tracks stacked one on the other perpendicular to the main track, each track comprising a fixed ring and a movable ring and each ring being constituted by a set of two coupled transmission lines, interrupted regularly and arranged in such a way with respect to each other that the electrical continuity of the ring is ensured.
  • phase and the amplitude are uniform at all points of the ring and whatever the angular position of a ring relative to the other, this phase and this amplitude of the signal are transmitted without alteration.
  • Figure 3 shows schematically in partial vertical section, a multi-way rotary joint according to 1! _invention. This joint is limited by the entry guide 12 of the main track transmitting the signals from the main radar in the most probable case where this joint is used with a main radar-secondary radar system, and the exit guide 13.
  • the outlet guide 13 is movable around the axis of rotation 2, relative to the fixed inlet guide 12 and at 1, there is the main track of the joint.
  • the other tracks which are annular are located around the main track in horizontal planes.
  • the fixed guide 12 is attached a metal body 14, having on its dimension parallel to the axis of rotation of the joint, a U-shape, one of the walls 15 of which has bosses 16 serving as support for a dielectric layer 17 serving itself supporting the fixed rings of the different tracks, rings identified by 18, 19, 20 and 180, 190, 200 for example if we consider 3 annular tracks in addition to the main track.
  • the wall 15 is moreover pierced with holes allowing passage to baluns 21, 22, 23.
  • a similar arrangement is made for the mobile part of the seal which comprises a metal body having two branches 24, 25 fixed to the mobile guide 13.
  • the wall 24 is pierced with holes allowing passage to baluns 26, 27, 28 for example and comprises bosses 29, 30 serving as support for a dielectric layer 31 itself serving as support for the movable rings 32, 33, 34 and 320, 330, 340. It can be seen that the dielectric layers or bands 17 and 31 face each other.
  • Figure 4 shows in horizontal section, an annular path of the seal, according to the invention showing how such a path is formed.
  • Each annular track has two concentric rings and each ring consists of two transmission lines interrupted regularly, and arranged relative to each other so that there is no electrical discontinuity.
  • the input ring thus comprises two transmission lines 18, 180 located on either side of a dielectric layer 17.
  • FIG. 4 we see very clearly the interruptions which are created in each of the lines, such as 35, 36 on line 18 and 350 on line 180. It is noted that the interruptions of the second line are found substantially opposite the middle of the sections of the first line.
  • the output ring movable relative to the input ring, also consists of two interrupted transmission lines 32, 320 arranged one relative to the other, on either side of a layer of dielectric 31, like the lines of the first ring.
  • the signals are transmitted between the two rings capacitively.
  • baluns are made necessary by the fact that, the lines being in principle closed on themselves, the phases at the points of attack must be reversed so that the continuity of the currents is assured on the lines.
  • FIG. 3 shows three annular paths, but it is easy to have 5 to 6. Their realization, by way of example is relatively easy.
  • the fixed parts and the mobile parts of the rings are grouped on strips produced according to the printed circuit technique.
  • lines 18-180; 19-190 and 20-200 produced in printed circuits are bonded on either side of a dielectric strip 17 fixed on the metal bosses 16 of the fixed metal body 14 of the joint.
  • lines 32-320, 33-330 and 34-340 fixed on either side of a dielectric strip 31 fixed on the metal bosses 29-30 of the movable body 12 of the joint.
  • the input and output baluns are also produced on printed circuit strips.
  • the thickness of the strips is approximately of the order of 1 to 2/10 mm, the air gaps of the order of 1 to 2 mm, the total height of a ring being substantially equal to 10 millimeters.
  • the length of the discontinuous strands of the lines is of the order of an eighth of the wavelength, a substantially optimal length.
  • the arrangement of the channels according to the invention comprises an adaptation system not described which is intended to compensate for the residual parasitic capacities.
  • the system exhibits good rotational stability, the residual variation of the amplitude being less than 0.1 dB and the residual variation of the phase being less than the degree.
  • a multi-way rotary joint has thus been described, having a relatively large number of annular tracks stacked one on the other around the main track of the joint, each track comprising a fixed ring and a movable ring, one and the other. another by two interrupted transmission lines, arranged in such a way that the signals are transmitted from one ring to the other by capacitive coupling.
