Definitions

  • the invention relates to a method and a system for defense against missiles which have explosives with a piezoelectric igniter.
  • Piezoelectric sensors are often used as impact fuses for triggering explosive payloads in unguided missiles, e.g. Rockets or projectiles used.
  • a typical example of such a missile is the Russian RPG-7 antitank grenade shown in FIG.
  • Remote ignition systems are known according to DE 2250 630 B2 with which under explosive charges are brought by ultrasound signals to detonation.
  • An explosive charge is assigned an ultrasonic receiver, with the the ultrasonic signal is received and processed electronically after conversion into an electrical signal.
  • the output signal of the ultrasonic receiver is fed to an electric detonator for triggering the detonation.
  • ultrasonic radiation is emitted to repel the approaching missile, which excites the piezoelectric detonator of the approaching missile to vibrate and thereby triggers the detonator, which was activated after the launch of the missile.
  • the triggering of the explosive payload thus takes place in the approach of the missile far away from the target.
  • the emitted ultrasonic radiation can penetrate the metal housing of the missile with only slight attenuation.
  • the ultrasound radiation can be emitted directionally or non-directionally.
  • the directed emission of ultrasonic energy preferably takes place in the form of a high-energy beam with a small opening angle.
  • an array of a plurality of ultrasonic transducers is preferably used.
  • an alignment of the radiated energy by targeted phase control of the signals of the individual ultrasonic transducers can be done (phased array technique).
  • the alignment is thus purely electronic without moving mechanical components.
  • the ultrasonic generator eg arranged on a turntable adjustable in azimuth and elevation.
  • the frequency of the ultrasonic radiation is chosen such that the piezoelectric igniter of the approaching missile is excited with its natural resonant frequency or a harmonic or subharmonic thereof.
  • the radiated ultrasound frequency can be varied over a certain frequency range, e.g. by linear frequency modulation.
  • the Doppler shift which arises as a result of the relative speed between the missile and the platform emitting the ultrasound radiation, is also advantageously taken into account.
  • the frequency of the ultrasonic radiation can be varied to compensate for uncertainties in the exact value of the Doppler frequency.
  • the method according to the invention is suitable for the defense of all guided and unguided missiles, eg rockets or projectiles.
  • the described system can be carried by both aircraft and land vehicles. Stationary applications on the ground are also possible.
  • a particular advantage of the system according to the invention is its very short reaction time, which is particularly important in the case of close-range bombardment.
  • a system S for carrying out the method according to the invention is shown schematically in FIG. 2. It comprises on two opposite parallel side surfaces in each case an array 2 of a plurality of ultrasonic transducers. With this device thus protection against approaching missiles in large parts of the left and right hemisphere is possible. If necessary, additional transducers can be added to achieve full coverage over 360 °.
  • the two ultrasonic arrays 2 are rigidly attached to the surface of the system S.
  • An alignment of the ultrasonic radiation 1 on the approaching missile 7.2 is carried out in the embodiment shown purely electronically via a corresponding phase control the individual ultrasonic transducer of an array 2. An additional, eg mechanical positioning is not necessary in this case.
  • the system further comprises four electro-optical missile warning sensors 4 for detecting a launch of the enemy missile (reference number 7.1 shows the missile in the starting phase). With the four sensors 4 shown a 360 ° -Abeckung is possible.
  • the illustrated missile warning sensors 4 are used in the present case as tracking sensors for tracking the approaching missile.
  • the system of Fig. 2 represents a very compact, easy to transport unit.
  • Fig. 3 shows a flowchart for carrying out the method according to the invention.
  • the launch of an enemy missile e.g. an anti-tank grenade RPG-7
  • the tracking sensor whose function is perceived here by the missile warning sensors
  • the positioning device aligns the ultrasound energy to be radiated with the missile.
  • the alignment takes into account the duration of the ultrasound beam to the target.
  • Ansch manend takes place the generation and directional radiation of the ultrasonic energy in the form of a bundled, high-energy acoustic beam. In the case of a purely electrical alignment, the functions of alignment and radiation of the ultrasonic radiation coincide.
