Abstract: An optical impact system controls munitions termination through sensing proximity to a target and preventing effects of countermeasures on false munitions termination. Embodiments can be implemented on in a variety of munitions such as small and mid caliber that can be applicable in non-lethal weapons and in weapons of high lethality with airburst capability for example and in guided air-to-ground and cruise missiles. Embodiments can improve accuracy, reliability and lethality of munitions depending on its designation without modification in a weapon itself and make the weapon resistant to optical countermeasures.

Abstract: A system and method for real time optical processing of images by simultaneous combining the variable set of images in selected spectral intervals. Spectral images at a plurality of spectral intervals are collected if needed. According to criteria established in a particular application, coefficients for an optimal combination of selected spectral intervals are calculated. Positive and negative images are continuously captured through the optical filter whose transmission spectrum adjusted to positive and negative coefficients of the optimal combination. Negative images are subtracted from positive images and a sequence of resulting optimized images is displayed in real time.

Abstract: A scanning antenna is disclosed including: a rotatable cylinder having an outer surface; a continuously, or steppingly, varying period conductive grating pattern of separated strips on the outer surface, the varying conductive grating pattern of separated strips defining a grating axis; and a first elongated dielectric waveguide defining a first waveguide axis, the first elongated dielectric waveguide being located proximally adjacent and alongside the varying conductive grating pattern of separated strips so as to evanescently couple electromagnetic signals with the first elongated dielectric waveguide. The scanning antenna provides advantages in that the gain is high.
