Optical signal injector system for HWIL testing of LADAR seekers

An optical signal injector (OSI) system has been developed for use in the hardware-in-the-loop (HWIL) testing of laser radar (LADAR) seekers. The OSI, in conjunction with a scene generator, generates optical signals simulating the return signals of a LADAR seeker and delivers them to a Unit Under Test (UUT). The signals produced by the OSI represent range and intensity (reflectivity) data of a target scene from a given HWIL scenario. The OSI has a modular architecture to allow for easy modification (e.g., operating wavelength, number of optical channels) and is primarily composed of commercial off-the-shelf (COTS) components to improve reliability and reduce cost, Presented here is a description of the OSI and its capabilities.
