    Abstract: Aircraft system and method detecting and present information relating to adverse airborne phenomena along an aircraft flight route. An imaging unit that includes an IR detector and a tunable spectral filter acquires IR images of the external environment, by acquiring wideband IR images when operating in a first mode and narrowband IR images respective of difference IR spectral bands when operating in a second mode. A data analysis unit detects and determines characteristics of adverse airborne phenomena in the environment based on at least the spectral signatures of environmental features in the acquired narrowband IR images. A display unit dynamically displays a visual representation of the detected adverse airborne phenomenon and its determined characteristics, overlaid onto a view of the external environment displayed to an operator of the aircraft. The visual representation may include variable visual attributes representing respective categories of characteristics of the detected adverse airborne phenomenon.

    Abstract: A device for image gating using an array of reflective elements is provided herein. The device includes an array of reflective elements, wherein each one of the reflective elements is movable within a range of a plurality of tilt positions, wherein the array is located at an image plane of the device, wherein the array is perpendicular to an optical axis of the device. The device further includes a control unit configured to control the reflective elements such that in at least some of the tilt positions, the reflective elements reflect the radiant flux at said image plane, to one or more projection planes. A gradual rotation of the reflective elements along the plurality of tilt positions result in a gradual increase or decrease in the intensity of the image reflected from the array of reflective elements while maintaining the image integrity.

    Abstract: A system and a method of generating a three-dimensional terrain model using one-dimensional interferometry of a rotating radar unit is provided herein. Height information is evaluated from phase differences between two echoes by applying a Kalman filter in relation to a phase confidence map that is generated from phase forward projections relating to formerly analyzed phase data. The radar system starts from a flat earth model and gathers height information of the actual terrain as the platform approaches it. Height ambiguities are corrected by removing redundant 2π multiples from the unwrapped phase difference between the echoes.
