Definitions

  • the invention relates to a device for guiding a missile with the aid of an electromagnetic beacon according to the preamble of claim 1.
  • an optical guide beam is generated by a light source, with which a missile is directed against a target from a launch base.
  • Means are provided to fan out the guide beam in such a way that the beam cross section consists of intersecting beams.
  • Means are also provided for modulating and deflecting the fanned out light beam, each bar being modulated differently.
  • the missile there is a receiver with photocells and control elements to steer the missile along the beacon against the target.
  • a guide beam is also generated with the aid of a light source in a path on which the missile is to move.
  • the guide beam cross-section is broken down into a checkerboard-like area, each field of the checkerboard-like cross-sectional area having its own code such that the receiver in the missile can recognize the field in which the guide beam cross-sectional area is located.
  • Digital frequency modulation of the beacon of a device for guiding a missile is e.g. in U.S. Patent 4,299,360.
  • two rotating coding disks are used, with passage openings which allow the guide beam to pass through and modulate the guide beam according to their arrangement on the disk.
  • a known device of this type see DE-A 3 311 349) the position of a manned missile is to be determined. So-called laser curtains are produced. If the manned missile penetrates one of these curtains, it receives the information at which point it has penetrated the forehand. With this known device, only the position of the manned missile is determined and communicated to the pilot of the missile so that he can correctly steer the missile. This known device thus serves only to determine the actual value and not the setpoint.
  • a target-tracking laser beam simultaneously forming the guide beam for a combat missile, which is launched to combat the attack missile.
  • the laser beam is constantly aimed at the target and forms a guide beam for guiding the defense projectile onto the attack projectile after the defense projectile has been fired.
  • a focused laser beam is aimed at the approaching target. This beam consists of three to four beams, which partially overlap. These beams have different frequencies, different modulation or different polarization.
  • the beam axis is determined by the coverage of the bundles.
  • a steering device for projectiles with a light source there is a steering device for projectiles with a light source.
  • the projectile can be directed with the light beam in two directions arranged at right angles to one another.
  • Two light beams with different wavelengths can be used for this. These beams are modulated at different frequencies. The modulation depends on the direction.
  • the beam can be divided.
  • a double-modulated laser beam can be divided into two partial beams.
  • a beam can also be used which is deflected alternately in two directions.
  • the beacon is frequency divided into four quadrants using four radiation sources, each of which has a different frequency.
  • the modulated radiation from the four sources is combined into a single beam with the desired spatial modulation.
  • the object which is to be achieved with the present invention is to create a simple device for guiding a missile, in which the risk that the missile inadvertently leaves the guide beam and can no longer be guided is as small as possible.
  • the device for guiding a missile with which this object is achieved has the features in the characterizing part of claim 1.
  • a chessboard-like scanning field is preferably generated with the aid of the device for deflecting the guide beam and each subfield is given its own code with the aid of the device for coding the guide beam.
  • a scanning field with circles or Spirals or any other pattern can be created.
  • the invention essentially consists in modulating a guide beam, in particular a CO 2 laser beam, first by means of an acousto-optical or electro-optical crystal with a code which contains the information to be transmitted.
  • the coded guide beam is deflected by a suitable device, in particular a deflection or scanning mirror, in such a way that it generates, for example, a checkerboard-like scanning field with eight by eight partial springs.
  • the deflected guide beam remains on each subfield until the required information has been transmitted and only then jumps to the next subfield.
  • a missile 6 is to be directed to a target 4 with the aid of a beacon 3.
  • a steering device 2 which directs the steering beam 3 towards the target 4 to be combated.
  • the directional axis 5 in the middle of the beacon 3 is indicated by dashed lines.
  • the missile 6 is to be directed against the target 4 in this guide beam 3.
  • the guide beam 3 is e.g. with the aid of a target tracking device, which is not described in detail here, is constantly aimed at the moving target 4. Instead of using the target tracking device, the guide beam 3 can be guided by hand to the target 4 until the missile 6 has reached the target 4.
  • the beacon 3 must have a sufficiently large cross-section to ensure that the missile 6 cannot fly out of the beacon after it is once in the beacon 3.
  • a guide beam 3 is generated which, compared to known guide beams, requires less power to generate it, i.e. the energy for generating the guide beam 3 is smaller than before, since only a subfield of the scanning beam is illuminated.
  • the coding should be able to be chosen as desired and should also be changeable as desired. This is not the case with known steering devices.
  • the data transmission performance should be high.
  • the laser 11 fed by a current source 10 generates a guide beam 3, the divergence of which is set by a device 12 for expanding the guide beam.
  • the guide beam is then encoded by a modulator 13.
  • the coded guide beam is changed by zoom optics 14 such that during the flight of the missile 6 e.g. the cross-section of the beacon is adjusted depending on the distance of the missile.
  • the focused and coded guide beam is deflected by a scanning mirror 15 and generates the checkerboard-like field 16.
  • An encoder 18 is connected to the modulator 13 via a driver 17 and a control element 20 is connected to the scanning mirror 15 via a driver 19.
  • the control element 20 is also connected to the zoom optics 14 via a driver 21. Both the encoder 18 and the control element 20 are connected to a common computer 22. Missiles 6 are indicated in various subfields 23 in the checkerboard-like scanning field 16 of the guide beam 3.
  • a frequency f a 80 Hz in the row direction, ie in the azimuth
  • the missile 6 is informed in which subfield 23 it is located. With 64 subfields 23, 3 bits are required to designate the column and another 3 bits to designate the row.
  • the missile 6 can be directed into the center of a partial field 23 by utilizing the natural beam distribution or by additional modulation.
  • the coding of the scanning field 16 described enables several missiles 6 to be steered simultaneously in different subfields 23 without the coding having to be changed.
  • coding can be used, in particular the analog methods: amplitude, frequency and phase modulation and the digital methods: on / off keying, frequency keying and phase shift keying.
  • the digital methods in particular phase shift keying, are preferred.
  • the coding is achieved by a phase jump compared to a reference signal.
  • a first frequency A corresponds to the logical assignment "0”
  • a second frequency B corresponds to the logical assignment "1”.
  • the rest of the coding corresponds to the phase shift keying just mentioned.
  • the encoder in the transmitter is synchronized with the decoder in the receiver before the launch of the missile.
  • the missile 30 has at its rear end a photodetector 31 with an upstream collecting lens and a narrowband filter which is connected to detector electronics 32.
  • detector electronics 32 there is an amplifier, a filter and a decoder. Special evaluation electronics in the missile are required to determine the center of the field.
  • a computer 33 is connected to the detector electronics 32. Control organs are used to guide the missile 30 ne 35 available, eg swiveling wings or nozzles.
  • the payload 36 for example an explosive charge, is located in the front part of the missile 30.
  • a current source 34 is provided to supply the various elements.
