Abstract
The development of a new generation PC-based array control electronics (PACE) system was completed during the first quarter of 2003 in the Kinetic Kill Vehicle Hardware-in-the-loop (KHILS) facility. This system replaces the bulky VME-based system that was the previous standard with more compact digital control electronics using field-programmable gate array (FPGA) technology hosted on a personal computer. The analog interface electronics (AIE) were redesigned to eliminate obsolete components and miniaturize the package for better compatibility with harsh environments. The resulting PACE system supports both Santa Barbara Infrared Inc. (SBIR) and Honeywell Technology Center's (HTC's) 512 x 512 legacy emitter array infrared projection devices as well as SBIR's upcoming 1024 x 1024 and next-generation 512 x 512 arrays. Two FPGA-based PCI boards enable this system to reconfigure the inputs, processing and outputs of the projection electronics through firmware loaded from the control PC. The increased flexibility provides potential for additional real-time functions such as distortion correction, convolution and calibration to be implemented along with nonuniformity correction (NUC) techniques by simply reconfiguring firmware. This paper describes the capabilities of the new PACE system in terms of current and future hardware-in-the-loop (HITL) requirements.
