Definitions
- the present invention relates to a dual mode seeker for a missile, a missile comprising such dual mode seeker and a method for assembling a dual mode seeker for a missile.
- the target In the guidance of missiles and other vehicles to a predesired target or destination, the target is usually acquired and tracked by means on the missile for detecting the target.
- Systems have been developed in the prior art for utilizing combinations of different detection methods in the seeker to maximize advantages afforded by each detection method.
- US 4,085,910 A discloses a dual mode optical seeker for guided missile control mounted in a nose of a missile.
- This seeker includes an infra-red sensor for sensing the orientation of the missile relative to an infra-red illuminated target, and an optical unit for determining the orientation of the missile relative to a visible target.
- the optical unit is stabilized in space about the pitch and yaw axes by means of a gyro stabilized platform unit which is separated therefrom and linked thereto by coupling rods which cause the optical unit to follow the stabilized platform in both yaw and elevation.
- This dual mode optical seeker may, however, be improved in view of the detection methods and in view of the arrangement within the missile.
- a dual mode seeker for a missile comprises a first sensing system configured to detect a target, a second sensing system configured to detect a target, and a space envelope configured to be arranged in a missile's nose.
- the first sensing system comprises an active radar transmitter and a radar receiver.
- the second sensing system comprises a passive optical detector.
- the space envelope comprises a first channel and a second channel arranged adjacent to each other in a seeker's radial direction.
- the first sensing system is arranged in the first channel and the second sensing system is arranged in the second channel of the space envelope.
- the present invention relates to an architecture or packaging scheme for a dual mode seeker.
- the dual mode seeker may be integrated into a missile's front section.
- the dual mode seeker comprises an assembly of an active radar transmitter, a radar receiver and a passive optical detector into a common space envelope.
- the dual mode seeker according to the present invention is improved in view of the detection methods, as a combination of an active radar detector and a passive optical detector is used. Thereby, the performance of the seeker in improved in view of a greater range, better accuracy, more frequency diversity, better tracking quality and better reliability. Further, the dual mode seeker is in particular suitable for the detection of small targets, very slow or very fast targets and helicopter detection.
- the dual mode seeker according to the present invention is further improved in view of the arrangement within the missile. It is possible to develop, use, integrate and upgrade the dual mode seeker independently into an arbitrary missile with only reduced temporal and financial effort. In other words, the temporal and financial efforts are reduced in view of development of the dual mode seeker, adaption of the dual mode seeker to a particular missile, production of the dual mode seeker, maintenance etc. In contrast to the prior art, the problem of a space envelope with a common gimbal for both sensing systems is solved and the use of an expensive dome transparent for both wavelengths of both sensing systems is avoided.
- the dual mode seeker according to the present invention can be made fully compliant to all customers' requirements.
- the dual mode seeker can be used for rolling and non-rolling missiles. Only minor missile shape adaptation with only minor impact to the missile dynamics performance is necessary. It is possible to use current radar and optical sensing systems with only a mechanical integration and only minor mechanical modifications.
- the active radar transmitter is a radiofrequency transmitter.
- the passive optical detector is configured for visible optics, infrared, Semi Active Laser and/or TV detection.
- the first channel is arranged above the second channel in the seeker's radial direction.
- both channels may be arranged such that e.g. the radar channel is on top and e.g. the infrared channel is on bottom.
- the first channel may also be arranged below the second channel in the seeker's radial direction.
- the first channel and the second channel may also be arranged next to each other or at any other possible angular position, e.g. depending on the weight balance.
- the first channel comprises a first aperture and the second channel comprises a second aperture.
- the first and the second apertures may differ from each other.
- the radar channel and e.g. the infrared channel may use separate apertures.
- the first and the second apertures may also be the same or may only partially differ from each other.
- the first channel comprises a first line of sight orientation and the second channel comprises a second line of sight orientation.
- the first and/or the second line of sight orientation may form an angle with a seeker's longitudinal direction between 0 and 45°, preferably between 0 and 25°, and more preferably between 0 and 10°. Thereby, an angle between the first and second channels and/or the first and second sensing system of up to 90° can be achieved.
- the seeker may further comprise control means configured to control the angles of the first and the second line of sight orientations independent of each other.
- first channel and the second channel are arranged with an offset to each other in the seeker's longitudinal direction.
- first sensing system and the second sensing system are arranged with an offset to each other in the seeker's longitudinal direction.
- the offset may allow minimizing a shadowing of one channel by the other, e.g. a shadowing of the infrared channel by the radar channel.
- the offset may be determined relative to a predetermined point of the channels and/or the sensing systems, as e.g. the apertures of the channels, the beginning, the gravity centre, the end of the sensing systems and the like.
- the offset may amount to between 0.5 to 50 cm, preferably between 1 and 30 cm, more preferably between 5 and 20 cm.
- the offset may also amount to between 1 and 30 % of the total missile's length, preferably between 2 and 20 %, more preferably between 3 and 10 %.
- the first channel is arranged essentially at the seeker's front end, while the second channel is further displaced to the seeker's back end.
- the first sensing system is arranged essentially at the seeker's front end, while the second sensing system is further displaced to the seeker's back end.
- first channel and the second channel are arranged parallel to each other in the seeker's radial direction.
- the first channel and the second channel may also be arranged slightly inclined to each other or slightly spreading relative to each other.
- the dual mode seeker further comprises a common mechanical reference for the first sensing system and the second sensing system.
- a missile comprising a dual mode seeker
- the dual mode seeker is arranged in a nose of the missile.
- a method for assembling a dual mode seeker for a missile comprises the following steps:
- the first and the second channels are arranged adjacent to each other in a seeker's radial direction.
- the first sensing system comprises an active radar - transmitter and a radar receiver.
- the second sensing system comprises a passive optical detector.
