Abstract: Provided is a detection system that utilizes high dynamic range, monolithically arranged, digital pixel sensors for situational awareness, targeting, tracking or locating. The detection system transmits a radially outwardly directed set of laser pulses into an environment, aspects of the pulses being reflected back by environmental elements to a single pixel array. The single pixel array scans volumetric space proximate the environment for profile characterization of the reflected aspects by the detection system in terms of intensity and multiplicity. The detection system is configured to compare this profile against a library of profiles of known environmental elements to distinguish between the environmental elements and a target. The detection system may be disposed about an outer periphery of a projectile for use in determining when the projectile is proximate the target for triggering an actionable element of the projectile, such as an initiator fuze for an explosive system.

Abstract: A dual-mode optical and RF reflector, and test system using the same. In one example the reflector is a mirror having a reflective surface including a first zone having a first surface precision, wherein a remainder of the reflective surface outside of the first zone has a second surface precision that is substantially lower than the first surface precision, the mirror being configured to collimate and reflect an RF signal from the reflective surface, and to collimate and reflect an optical signal from the first zone.

Abstract: A multimode radiation source is disclosed. One embodiment includes a waveguide radiator and an orthomode transducer coupled to the waveguide radiator to provide a first signal to the waveguide radiator. The waveguide radiator is configured to receive the first signal and to radiate the first signal at a first location as a first spherical wave signal with a first phase center. The multimode source also includes transmission medium coupled to the waveguide radiator and configured to radiate a second signal and a third signal from the first location as a second spherical wave and a third spherical wave with substantially the first phase center.
