Definitions
- the invention is based on a combination antenna according to the preamble of Claim 1.
- DE 35 44 092 A1 describes GHz multi-range antennas for small seekers in Projectiles known to be distributed concentrically evenly around a central axis at least three broadband spiral antennas for receiving radar signals are arranged for intercepting radar-fighting missiles; being in Center of the spiral antennas several millimeter wave antennas behind a dielectric Lens with constant dielectric constant are additionally provided, to realize a dual-mode seeker head.
- From US 3 943 520 A is for installation in a conically tapered environment suitable dielectric wedge antenna with capacitive tuning of the feed opposite at its apex known.
- the present invention is based on the technical problem, a proximity fuse for an artillery projectile in terms of its antenna structure interpret that they can also be used for satellite navigation tasks and at the imported artillery ammunition can be easily retrofitted.
- the tip of a modern artillery projectile usually contains in the direction of flight behind one concentrically arranged programming coil a circuit module with at least one Signal processor for the evaluation electronics, and behind it fuse and ignition devices. Since the tip is screwed to the fuselage of the projectile, it is only used when it is in use to apply, it is also easily exchangeable. It turns out that in the the interior of the tip tapering towards the front is still free space immediately in front of the coil for additional installation of the carrier plate for the antenna structure of the navigation receiver is the receiver itself, i.e. the signal processing for winning and The satellite navigation information can be evaluated in the module located behind the coil be included.
- the antenna structure i.e. the geometry of the electrically conductive surfaces on the two Sides of the dielectric carrier disc, is preferably in relation to the axis of rotation of the Projectile designed in such a way that a point-symmetrical antenna pattern is set to rotation-dependent interferences such as, in particular, amplitude modulations of the received signals to avoid if possible.
- the flat cylindrical disc-shaped one Antenna structure serves as both systems (navigation receiver and range radar) Antenna system.
- GPS reception is all in one Radar proximity detonator enables without the need for space for separate antennas So in a confined space with the same antenna, the navigation information and the radar echo winnable.
- FIG. 1 The sketched in Fig. 1 in broken view and partially in axial longitudinal section Tip 11 of an artillery projectile 12 carries a ballistic in front of its metallic housing 13
- Hood 14 in the form of a high-frequency permeable plastic radome made of thermoplastic Material like Teflon.
- the level of the joint between housing 13 and The hood 14 is used by the circuit module 15 for various signal processing tasks protrudes through a large area in the projectile flight direction in front of it under the radome hood 14
- Programming coil 16 for the ignition function of the circuit mode 15 carries.
- the interior of the hood 14 in front of the programming coil 16 is in itself the dipole or helix structure the transmit / receive antenna 17 of a distance radar 18 (FIG. 2) is arranged.
- This radar antenna 17 is now concentric in front of the programming coil as a dual-mode planar antenna 16 trained because they are also the receiving antenna 19 of a satellite navigation receiver 20 serves.
- the radar antenna 17 and the navigation antenna 19 are thus to a combination antenna 21 on an approximately 2.5 mm thick disc (at approximately ten times Diameter), the lamination of which resonates at between the 4th GHz and 5 GHz radar frequency in the C-band is tuned.
- the combination antenna 21 simultaneously for both operation of the radar 18 and also for the operation of the navigation receiver 20 is optimized.
- the combination antenna 21 is constructed as a dielectric flat antenna, based on the two mutually opposite surfaces of, for example, a circular disk-shaped dielectric Carrier disc 22 (exaggeratedly thick in the drawing for illustration) carries electrically conductive surface structures, for example from an original extensive lamination are etched out.
- the window lamination consists of a front surface 24.1 and one in all directions beyond its boundary back surface 24.2.
- Antenna characteristic is the carrier disc 22 concentrically transverse to the axis 23 in front of the Programming coil 16 held.
- a changeover switch 25 which, in the interest of the least possible signal loss is preferably implemented as a PIN diode switch.
- This switchover takes place from a control stage 26 in accordance with the inductance at the coil 16 predetermined programming of the use of the radar operation only in the final phase of Mission, i.e. after a predefinable minimum flight time.
- the navigation receiver 20 is connected to the combination antenna 21 connected to record the current trajectory using satellite navigation or to be able to correct it if necessary.
- the projectile 12 equipped according to the invention thus has a replaceable tip 11 under its ballistic radome hood 14 is an easily integrated combination antenna 21 with a hemispherical view in the direction of flight ahead, matching both the fundamental frequency the radar 17 of a distance igniter as well as the third harmonic of the carrier frequency corresponds to a satellite navigation receiver 20, so that a combination antenna 21 both systems can be operated in a confined space.
- the distance radar 18 is only put into operation when the navigation receiver 20 is switched off because the projectile 12 is corrected on it Trajectory has reached the target area.
