Definitions
- the invention relates to a missile weapon system with a Search head optics and an instruction processor according to claim 1.
- Such weapon systems are known per se.
- the missile is after Firing completely on its own when searching for a target.
- a gimbal-mounted seeker head camera and a tracker equipped by successive image comparison using a Correlation procedure pursues its assigned goal until hit, the search head moves completely autonomously after the launch and cannot be influenced.
- the missile - or its "instruction processor” (alignment processor) -vor specified the destination to be approached for departure or he / she to this destination be briefed.
- Image comparison in which images of the rifle sight with those of the Search head compared and correlated.
- the search head has a significantly smaller field of view compared to the rifle sight, so see just a section of the larger visor image.
- Agreement the alignment processor executes both images continuously, the Comparison is made so that from the top left corner of the search header image Row by row and column by column in the sighting image and for each position the correlation coefficient or a related criterion is determined. Where the correlation coefficient is maximum, it is Probability that both images are congruent is greatest.
- the seeker head is now a fixed focal length possesses, the shooter can not determine the image section himself, but the search head is dependent on "what it gets to see".
- the Focal length of the viewfinder optics is dimensioned so that a normal one Tank target 500 m away - this is the minimum distance - still full fits into the picture.
- this has the disadvantage that the goal is in the Maximum distance of about 4.5 km is relatively small. (approx. 4 samples).
- the optical axis of the visor has from the optical axis of the Seeker a distance caused by the carrier (helicopter), so a parallax that is about 5 m in height and width. So that's the Perspective from the seeker head to the target other than from the sight.
- the alignment processor it is essential that seeker and visor optics see the same. But this is not given when there are foreground or background objects in the image ( Figure), which is to be addressed as a normal case. But this makes the Image comparison deteriorates significantly and leads to a large one Einweiscosm.
- a missile weapon system is known from US Pat. No. 3,986,682 become, in which by comparison of visor and Search head images continuously using a correlation method tracked, the image size of the homing optics small from the start is chosen.
- DE 33 34 729 A1 describes a method for aligning a Target seeker known a self-directed missile, in which a Image containing target and an image generated by the seeker with the help an image correlation can be adapted to each other.
- the present invention has for its object a weapon system to create the type mentioned, in which the Probability of instruction of at least 85% achieved and guaranteed and the alignment processor almost due to residual stabilization errors is undisturbed, the harmonization near the ground and the search header in the Resolution is improved.
- the Marking box is a rectangular, not process-generated by the display fully extended white frame with indicated corners. This is currently designed square and its size is preset. The shooter can now the marking box via the operator controls either enlarge or reduce, zoom so to speak.
- the operational State - ie "enlarge” or “reduce” - is on the MIL bus communicated to the fire control computer (FCC).
- FCC fire control computer
- the current check box size that the Tracker for setting the trackbox size is communicated by the FCC.
- the search head regulates its current actual value to the setpoint commanded by the FCC and gives each frame the currently achieved field of view FCC until it determines that the fields of view match.
- the Loop can be maintained as long as the shooter in turn readjusted at the "Operator Controls".
- the Search head image is rotationally symmetrical and only the part with the Visor image section can be compared that within a inscribed square.
- the sensor ratio is geometric to be taken into account by a factor ⁇ 2
- an appropriate marker box size is for moving Aiming including the carrier movements is more difficult than with standing Aim and unmoved carrier.
- the carrier movements are through Minimize activation of the background tracker so that only the Relative movement of the target is to be taken into account.
- this image section must be can be compared with an equally large section of the search header image.
- the search head with a zoom lens is now proposed equipment that is able to reduce the field of view until the The target is still "filling the picture" even at maximum target distance.
- the the corresponding field of view is determined by the FCC (Fire Control Computer) carried out via the weapon system bus.

Description
Claims (1)
- Flugkörper-Waffensystem mit einem kardanisch aufgehängten Zielsuchkopf und einem Einweisungsprozessor (Tracker), der durch Vergleich von zur Deckung gebrachter Visier- und Suchkopfbilder mittels eines Korrelationsverfahrens kontinuierlich sein Ziel ermittelt, dadurch gekennzeichnet, daßa) der Zielmarkierungsrahmen im Visierbild zur Reduzierung des Einflusses der Parallaxe auf die Korrelation durch Verkleinerung oder Vergrößerung an die Größe des Zieles anpaßbar ist und in der gewählten Größe der Zielsuchkopfoptik eingegeben wird,b) der Zielsuchkopf mit einem an die Waffensystemreichweite angepaßten Zoomobjektiv versehen ist, welches das Sehfeld soweit verkleinert, bis das Ziel im Deckungsbild in allen Zielentfernungen immer mindestens nahezu "bildfüllend" dargestellt wird,c) die auf den Zielsuchkopf bzw. dessen Zoomoptik einwirkenden Vibrationspegel durch Einschalten des bordeigenen Hintergrundtrackers weitgehend eliminiert werden undd) durch Anpassung der Auflösung beider Sensoren für die Zielübergabe ein Wert für die Korrrelationsgröße vorgegeben wird.
