Definitions
- the invention relates to a trigger sensor for the warhead of a missile, which has at least two ring-shaped arrangements of a plurality of optical sensors on its circumference, the detection areas of which open conically in the direction of flight.
- Such missiles are used to combat incoming enemy missiles.
- a trigger sensor for the warhead of a missile is known, which is intended to cause timely triggering when a target is flying past.
- the missile has four rings, each with several sensors, in which the detection areas of two sensors open conically in the direction of flight, while the others are arranged perpendicular to the direction of flight.
- the speed of the target to be combated can only be determined after the detection area of the last of the four sensor rings has been penetrated. This precludes the use of such a trigger sensor for a warhead that can be aimed at a target.
- no information is given on the type of sensors used.
- the invention has for its object to provide a trigger sensor for a warhead in such a way that it can be used both with a directional warhead and with a sheaf warhead.
- the particular advantages of the trigger sensor according to the invention are the simple construction and the simultaneous usability for directional warheads and splintered warheads.
- the detection areas E1, E2 open conically in the direction of flight, the rear sensor ring R2 having a slightly larger opening angle than the front sensor ring R1, so that the detection areas do not intersect.
- a warhead (not shown) is arranged in the missile FK, which has a radially circumferential direction of action W when a splinter-warhead is used.
- the active axis W can take any direction in the plane shown in FIG. 1 and spanned by the rays W.
- Each of the sensor rings R1, R2 consists of a plurality of individual active laser range finders, which are arranged such that they span the detection areas E1, E2 by means of uniformly distributed individual beams.
- Laser rangefinders with bundling of the individual beams to less than 3 mrad are provided for the planned application situation.
- the mutual beam distance is about 30 centimeters at a distance of 10 meters from the missile. This results in a number of 150 or 90 individual radiators per sensor ring R1, R2.
- the transmitter diodes are combined into groups of 5 or 3 elements to form a structural unit. Between these are the common receiving optics EO arranged for 5 or 3 receiving diodes ED.
- the transmitter diodes SD are pre-adjusted on the carrier of the assembly. They are equipped with centering converging lenses (so-called Selfoc lenses).
- the sensor rings R1, R2 can also be made twice, as shown in FIG. 3, the beams of the laser range finder then being aligned almost parallel within a respective detection range E1, E2.
- the warhead can also be arranged in front of the sensor rings R1, R2, as seen in the direction of flight, since the detection areas E1, E2 facing forward, in conjunction with the distance measurement, allow the ignition timing to be calculated much earlier than is possible with previously known embodiments of missiles.
- the evaluation of the output signals a, b of the plurality of laser range finders LEM 1 (a ... n), LEM 2 (a ... n) is shown in simplified form.
- the laser range finder the beam of which strikes the target, generates output signals a, b.
- These are fed to the coordinate computer KR1, KR2 and the part of the computer A which calculates the triggering time. From the measured directions, the distances d1, d2 are calculated in the coordinate computer, which together with the time difference between the individual penetration points through the detection areas E1, E2 result in the trajectory T of the target. Taking into account the lead time and the system-related delay times, the optimal triggering time is finally determined in the ignition circuit Z.
- the laser rangefinders are combined into groups and that effective noise suppression is provided for the output signals of the idle receivers.
- the trigger sensor anyway to couple the search head present in the missile and to use its signals for switching on the trigger sensor when approaching a target and for pre-instruction on the expected target trajectory.
