Abstract: A method for displaying point-of-interest coordinate locations in perspective images and for coordinate-based information transfer between perspective images on different platforms includes providing a shared reference image of a region overlapping the field of view of the perspective view. The perspective view is then correlated with the shared reference image so as to generate a mapping between the two views. This mapping is then used to derive a location of a given coordinate from the shared reference image within the perspective view and the location is indicated in the context of the perspective view on a display.

Abstract: System for simulating one or more sub-systems of a tested system includes: (a) a sequence diagram storage and engine unit containing a predefined sequence diagram defining the intercommunication of messages between the various sub-systems of a real system in terms of at least time, message name, issuing sub-system, and destination sub-system. An indicator indicates to said sequence diagram storage and engine unit, those missing sub-systems, which have to be simulated. A receiver within said sequence diagram storage and engine unit receives an activation signal for the sequence diagram, and for eliminating all those messages in the sequence diagram relating to non-missing sub-systems, while maintaining those messages relating to missing sub-systems.

Abstract: A warhead configuration for forming a hole through a wall of a target, the warhead configuration comprising a charge of explosive material and a liner. The charge has an axis and a front surface. The front surface includes two annular front surface portions, an inner and an outer annular portion, circumscribing the axis. Each of the annular front surface portions is configured so as to exhibit a concave profile as viewed in a cross-section through the charge parallel to the axis. The liner includes a first liner disposed adjacent to the inner annular portion and a second liner disposed adjacent to the outer annular portion such that, when the charge is detonated, material from the first liner is formed into a first expanding explosively formed ring and material from the second liner is formed into a second explosively formed ring.

Abstract: A system for slowing an air vehicle, including an independently supported aerodynamic drag device designed so that, after contact is made between the flying air vehicle and the aerodynamic drag device, one or more parts of the aerodynamic drag device are carried along by the air vehicle thereby decelerating the air vehicle, so that a majority of a kinetic energy dissipation of a combination of the air vehicle and the aerodynamic drag device is due to an aerodynamic drag of the aerodynamic drag device.

Abstract: A method for reducing the effects of background radiation introduced into gaseous plume spectral data obtained by an aerial imaging sensor, includes capturing spectral data of a gaseous plume with its obscured background along a first line of observation and capturing a second image of the previously obscured background along a different line of observation. The parallax shift of the plume enables the visual access needed to capture the radiometric data emanating exclusively from the background. The images are then corresponded on a pixel-by-pixel basis to produce a mapping. An image-processing algorithm is applied to the mapped images to reducing the effects of background radiation and derive information about the content of the plume.

Abstract: A terrestrial imaging device includes an objective lens which accepts light within an intrinsic angular field of view onto a focal plane and two pairs of plane mirrors. The first pair of plane mirrors reflects a first light incoming ray sequentially to produce first and second reflected light rays within a roughly horizontal plane, the second reflected ray being focused by the objective lens on the focal plane. The second pair of plane mirrors reflects a second incoming ray sequentially to produce third and fourth reflected light rays within a roughly vertical plane, the fourth reflected light ray being focused by the objective lens on the focal plane.

Abstract: An imaging system (30, 30?) and corresponding method has a two-dimensional imaging sensor array (32) and an associated optical system. The optical system includes at least one optical arrangement (34, 36a, 36b) defining a field of view (38a, 38b) of given angular dimensions and an optical switching mechanism (40) for alternately switching an optical axis of the imaging system between two directions (42a, 42b). The optical switching mechanism and the optical arrangement(s) are deployed such that the imaging sensor array generates images of at least two generally non-overlapping fields of view of equal angular dimensions and with diverging optical axes in fixed spatial relation. Rapid switching between the fields of view allows quasi-continuous monitoring of a larger field of view than would otherwise be possible while maintaining sensitivity to transient events. Also disclosed is an infrared search and tracking system based on such imaging systems.

A detection arrangement is configured to direct part of the transmitted pulses and a reflected signal from each of the directions onto a common detector. The output of the detector is processed by a processing system to derive range data associated with each of the directions by coherent detection of the reflected signals employing the part of the transmitted pulses as a local oscillator.

Abstract: The pylon of the present invention provides damping of vibrations transferred in both directions between the aircraft and the payload. That is, the pylon of the present invention damps the effects of aircraft vibrations on the payload as well as the effects of payload vibrations on the aircraft. This is accomplished in the present invention by substantially eliminating any rigid connection between the aircraft and the payload under normal operational conditions. Support of the payload is provided by a plurality of resilient suspension elements that are attached to both a base element and a payload interface element. The attachment is such that the payload element is suspended below the base element. Thus configured, the resilient suspension elements dampen the transmission of vibrations between the payload interface element and the base element.

Abstract: A method for improving nighttime visual awareness of a pilot flying an aircraft carrying an air-to-air missile including one or more one gimbaled imaging sensor. The method includes providing a helmet for the pilot, a helmet tracking system for determining the attitude of the helmet relative to the aircraft, and a helmet-mounted display.

The determining and the displaying are performed so that the image displayed on the helmet-mounted display viewed by the pilot is spatially aligned with the scene viewed by the imaging sensor.

Abstract: A LADAR system includes a detector optical arrangement defining a current optical field of view. An illumination subsystem without moving parts transmits pulsed illumination at different times to each of a number of illumination sub-regions of the current optical field of view, and a detection subsystem, including one or more detectors, detects reflected illumination from a corresponding one or more detection sub-region of the current optical field of view. Each of the detection sub-regions overlaps illumination sub-regions so that an overlap of each of the illumination sub-regions with the detection sub-region defines a LADAR image pixel of resolution finer than the detection sub-region.

Abstract: A method for identifying bad pixels in a matrix imaging sensor comprises moving the matrix sensor in a prescribed motion with respect to a background landscape (FIG. 1, 10), acquiring a combined image of the landscape, and identifying bad pixels (16) in the matrix sensor from the combined image. The identification is aided by preferably applying filtering to the combined image. The prescribed motion is preferably rotation of the sensor or translation of the sensor around a circle, and the combined image includes a plurality of preferably similar landscape images. The identification of the bad pixels is performed on-line, in real-time, without requiring the use of a black body.

In some embodiments, the rate of flow out of the pump does not change when one tank becomes empty before another.
