Definitions

  • the invention is based on a phase-controlled antenna according to the preambles of claims 1 and 2.
  • Such antennas in particular for radar applications, are known, for example from the published documents DE-A 38 03 779 and DE-A 39 02 739.
  • the arrangements described therein essentially consist of a multiplicity of transmit / receive radiator elements which are arranged in a line or matrix .
  • These transmit / receive radiator elements are connected to a known transmit / receive arrangement via a phase shifter arrangement, a distribution network and a transmit / receive changeover switch, a circulator.
  • the distribution network and the phase shifter arrangement serve for the electronic shaping and / or pivoting of a transmitting / receiving lobe.
  • the send / receive switch the transmit and receive signals are decoupled.
  • the invention is therefore based on the object of improving a generic arrangement such that the use of technically complex components, in particular the circulator, is eliminated.
  • the invention is based on the use of a series feed line which has a plurality of coupling / decoupling points for coupling / decoupling the transmission / reception signals used and also two gates for coupling the transmission and reception arrangement.
  • a series feed line and a distribution and phase control network coupled to it With such a series feed line and a distribution and phase control network coupled to it, a transmission / reception switchover is surprisingly possible without the need for a separate transmission / reception switchover, in particular a circulator.
  • a series feed line consists of a waveguide suitable for the transmission / reception wavelengths used, for example a waveguide, in which a predeterminable number of coupling points, for example coupling slots, are arranged at predeterminable, equidistant intervals in the direction of propagation of the guided wave.
  • the waveguide WE has two gates T1, T2 and a predeterminable number of slots S1 to Sn, where n is a predeterminable integer.
  • the slots S1 to Sn are designed as coupling / decoupling slots for the wave guided in the waveguide WE (wavelength ⁇ ) and are at a distance of ⁇ / 2 in the longitudinal direction of the waveguide WE (direction of propagation of the wave).
  • An associated connecting waveguide VW1 to VWn (connecting waveguide) is coupled to each of the coupling / decoupling slots S1 to Sn.
  • phase adjuster networks which are not shown but which are known per se from the publications mentioned at the outset and which are designated by PHN in FIG.
  • the transmitting / receiving radiator elements are connected. If, for example, a transmission signal is now coupled into the gate 1 as a continuous wave, portions are coupled out at the coupling / decoupling slots S1 to Sn and passed to the transmitting / receiving radiating elements via the connecting waveguides VW1 to VWn and the phase adjusters. A pivoting of the transmission lobe (transmission characteristic) is then possible in a known manner by means of the phase adjuster.
  • the signal received by the transmission / reception radiator elements for example the echo signals belonging to the transmission signal, is now conducted into the waveguide WE via the phase adjusters of the phase network and the connecting waveguides VW1 to VWn. It is now advantageously possible to set the phase adjuster in this case of reception in such a way that the received signal arising in the waveguide WE can be coupled out at the second gate T2. At most, a negligible (reflection) component arises at the first gate T1.
  • the received signal generated at the second gate T2 is then passed to a (radar) receiver in a manner known per se, for example via waveguides, and evaluated there.
  • the arrangement described can be produced with a large number of waveguides, for example in so-called stripline or microstrip or coaxial technology.
  • FIG. 2 shows a further example in which two divider networks TN1, TN2 are arranged symmetrically with respect to a symmetry line SY.
  • Each of the divider networks TN1, TN2 is constructed, for example, in accordance with FIG. 1, but with the difference that a single coupling / decoupling connection EA1, EA2 is present in each case.
  • These coupling / decoupling connections correspond, for example, to gate T1 (FIG. 1), gate T2 (FIG. 1) being terminated with a terminating resistor (RF sump).
  • the divider networks TN1, TN2 are coupled to transmit / receive radiator elements via phaser networks PHN.
  • the coupling / decoupling connections EA1, EA2 are connected to gates of a coupler KO which is designed as a 3 dB hybrid, for example as a so-called "magic T” or as a 3 dB directional coupler.
  • This coupler KO also has a (transmit) gate T1 and a (receive) gate T2, the function of which has already been described with reference to FIG. 1.
  • the arrangement described with reference to FIG. 2 corresponds in the (radar) antenna technology to an arrangement for generating sum / difference diagrams.
  • phase adjuster in the case of a transmission signal coupled into gate T1 in such a way that a sum diagram known from radar technology is emitted (emitted) by the transmission / reception radiator elements.
  • reception it is also possible, as described with reference to FIG. 1, to use the phase adjuster in this way set that the received signal of the same sum diagram can be coupled out at gate T2.
  • the necessary changeover of the phase adjuster is 180 ° in one of the two halves of the phase adjuster network.
  • a desired high decoupling for example greater than 20 dB, can be produced between the gates T1, T2 if the coupler KO (hybrid) has a correspondingly high decoupling with reflection-free termination and care is also taken to ensure that the arrangement shown in FIG of the guided waves is symmetrical and also has the lowest possible reflection factors.
  • the arrangement described can advantageously also be produced using different line technology, as already described with reference to FIG. 1.
  • the example according to FIG. 3 differs from that according to FIG. 2 only by the connection diagram of the transmitting / receiving radiator elements.
  • the arrangement according to FIG. 3 has a type of alternating connection. With consecutively numbered transmit / receive radiator elements, all odd-numbered transmit / receive radiator elements are coupled to one divider network, for example TN1, and all even-numbered ones to the other, here TN2.
  • This interlocking coupling makes it possible to generate a summation diagram for a received signal at gate T1, while a signal coupled out at gate T2 does not correspond to a difference diagram.
  • This arrangement can also advantageously be produced in the technologies already mentioned.
  • phase shifters phase shifters
  • phase shifters phase shifters
  • the invention is particularly advantageous when non-reciprocal phase adjusters (ferrite phase shifters) are already used in the transmitting / receiving arrangement, since these phase adjusters have to be switched over with every transmission / reception switching operation. In this switching process, the described additional phase adjustment can then be carried out without more effort.
