Definitions

  • the invention is based on a phased array antenna according to the preamble of claim 1
  • Such antennas in particular for radar applications, are known, for example from the published patent applications DE-A 3803779 and DE-A 3902739.
  • the described there Arrangements consist essentially of a multiplicity of transmitting / receiving radiator elements, which are arranged in line or matrix form.
  • This Transceiver elements are via a phase shifter arrangement Distribution network and a send / receive switch, a circulator, to a connected to known transmission / reception arrangement.
  • the distribution network serves this purpose and the phase shifter assembly for electronic forming and / or pivoting a transmitting / receiving lobe. Through the send / Emp switcher a decoupling of the transmit and receive signals is achieved.
  • the invention is therefore based on the object, a generic arrangement to improve that a use of technically complex components, in particular the circulator, is eliminated.
  • the invention is based on the use of a series feed line, the more On / Off coupling points for coupling / uncoupling the used transmit / receive signals has and also two gates for coupling the transmitting and the receiving device.
  • a series feed line and a coupled thereto Distributor and phaser network is surprisingly a transmit / receive switch possible without a separate send / receive switch, especially a circulator, is necessary.
  • a standard supply line consists of one for the used transmission / reception wavelengths suitable waveguide, for example a waveguide in which in the propagation direction of the guided Wave in predeterminable, equidistant intervals a predetermined number of coupling points, For example, coupling slots are arranged.
  • a guided in the waveguide transmission signal in a predetermined Number which corresponds to the number of coupling points, of individual transmission signals split with predetermined transmission power.
  • This one is special depends on the design of the coupling points, which is familiar to a person skilled in the art is.
  • These single transmit signals, for example, a full line are assigned by radiator elements are then via distribution and phaser networks fed to the individual transmit / receive radiator elements.
  • Fig. 1 shows a waveguide WE, for example a waveguide with a rectangular Cross section for the 5 GHz range.
  • the waveguide WE has two ports T1, T2 and a predeterminable number of slots S1 to Sn, where n is a predefinable integer Number is.
  • the slots S1 to Sn are formed as input / Auskoppelschlitze for in the Waveguide WE guided wave (wavelength A) and have in the longitudinal direction of the Waveguide WE (propagation direction of the wave) a distance of ⁇ / 2.
  • At each the input / output slots S1 to Sn is an associated connection waveguide VW1 to VWn (connecting waveguide) coupled.
  • the transmitting / receiving radiator elements connected.
  • a transmission signal as a continuous Wave coupled into the gate 1 so are at the input / Auskoppelschlitzen S1 to Sn shares decoupled and via the connecting waveguide VW1 to VWn and the phase adjuster is routed to the transmit / receive radiator elements.
  • the phaser is then in a known manner, a pivoting of the transmitting lobe (transmission characteristic) possible.
  • the received from the transmitting / receiving radiator elements is now Signal, for example, belonging to the transmission signal echo signals, via the Phase adjuster of the phase network and the connecting waveguides VW1 to VWn guided in the waveguide WE. It is now advantageously possible, the phaser in this receiving case to adjust such that in the waveguide WE resulting receiving signal to the second port T2 can be coupled out.
  • T1 arises at most a negligible (reflection) share.
  • the received signal resulting from the second gate T2 is then known per se Way, for example via waveguide, directed to a (radar) receiver and there evaluated.
  • phase switching operations is a variety of currently conventional phaser suitable for example, delay lines.
  • the invention is particularly advantageous when already non-reciprocal phase adjuster (ferrite phase shifter) in the transmit / receive arrangement can be used, as these phase shifters each transmit / receive switching have to be switched. In this switching process is then the described additional phase adjustment without more Effort feasible.
