Abstract:
A gimbal transmission cable management system is disclosed. The system can include a first gimbal portion and a second gimbal portion rotatable relative to one another to provide rotation about a gimbal axis. The system can also include a cable retainer fixed relative to one of the first and second gimbal portions and defining a cable volume between the cable retainer and at least one of the first and second gimbal portions. In addition, the system can include a transmission cable coiled about the gimbal axis within the cable volume. Bi-directional relative rotation of the first and second gimbal portions can alternately coil and uncoil a portion of the transmission cable about the gimbal axis within the cable volume.
Abstract:
A range extension unit extends the range of a guided mortar bomb. The range extension unit includes a housing interface defining an internal cup that receives a rear portion of a guided mortar bomb, wherein the housing interface covers a rear portion of the mortar bomb. The housing interface, when coupled to the mortar bomb, collectively forms an aerodynamically shaped body with the mortar bomb. At least two deployable wings are attached to the housing interface, wherein the wings transition between a retracted state and a deployed state.
Abstract:
A method of controlling movement of an agent operating within an autonomous system includes determining, using a processing device associated with the agent, at least one point of interest (POI) within an area of operation by the autonomous system; determining, from the at least one POI, a POI of highest attraction for the agent and calculating an attraction force for the agent, based on the location of the POI of highest attraction; determining proximity of the agent to one or more additional agents operating within the autonomous system, and calculating a repulsion force for the agent so as to maintain a minimum separating distance between the agent and the one or more additional agents; calculating a resultant force for the agent based on the attraction force and the repulsion force; and changing a direction of the agent based on the resultant force.
Abstract:
The presently disclosed subject matter includes a laser system and a respective method of detecting a signal reflected from a target illuminated by a modulated CW light source configured to generate a modulated laser signal at a predefined modulation frequency. A signal comprising true laser signal portions reflected from said target, and noise is received; the signal is filtered for selecting laser signal portions at a modulation frequency band; and the true signal portions in the signal are detected, if the energy at the modulation frequency band is greater than a given threshold.
Abstract:
A laser jammer configured for being a part of a countermeasure system. The system comprises a stage having an axis of rotation and laser source mounted on the stage. The laser source is configured for emitting a laser beam having an optical axis perpendicular to the axis of rotation. The laser has a first spread in a first plane parallel to the rotation axis of the stage and including the optical axis, and a second spread in a second plane perpendicular to the first plane and including the optical axis. The first spread is greater than the second spread.
Abstract:
A communication interface for a laser-guided projectile is configured to use the SAL seeker on board the laser-guided projectile as a communication link. A communication device generates a pulsed optical beam that overlaps the detection band of the SAL seeker. The pulsed optical beam is encoded with data for the SAL seeker. Computer-readable program code is loaded into and executed by the seeker's signal processor to process the signals generated in response to the pulsed optical beam to extract the data for the SAL seeker. Data is typically coupled to the projectile pre-launch but may be coupled in flight to the target.
Abstract:
Die Erfindung geht aus von einem Verfahren zum Erfassen eines Ziels (8) durch einen von einer Trägerplattform (4) gehaltenen Flugkörper (2) mit einem Suchkopf, bei dem das Ziel (8) anvisiert wird und Zieldaten an ein Suchersystem (12) des Flugkörpers (2) übergeben werden. Es wird vorgeschlagen, dass das Suchersystem (12) des Flugkörpers (2) das Ziel (8 als solches anhand der übergebenen Zieldaten erfasst während dem Suchkopf die Sicht auf das Ziel (8) versperrt ist. Das Ziel kann durch den noch in der Trägerplattform verborgenen Flugkörper erfasst werden, ohne dass auf eine gute Tarnungseigenschaft der Trägerplattform verzichtet werden muss.
Abstract:
In an embodiment of methods and systems for optical focusing for laser guided seekers using negative index metamaterial, the methods and systems comprise a light focusing system comprising: a lens comprising a negative index metamaterial to focus at least one selected wavelength while defocusing other wavelengths, and a sensor upon which the lens focuses the selected wavelength.
Abstract:
An optical imaging system is provided for an airborne platform or the like, including an image acquisition unit having an optical axis and configured for providing images in a direction along said axis, the image acquisition unit being mounted to a pointing mechanism configured for selectively pointing said optical axis in a desired direction. The system also has an optical shield configured for shielding said image acquisition unit from receiving undesired electromagnetic radiation from at least one direction different from said desired direction.
Abstract:
