Amherst Systems has developed a Universal Programmable Interface (UPI) for real-time modeling of sensor effects and other image processing functions. To properly test infrared sensors, the UPI must simulate by-passed sensor components, simulate optical blurring and distortion, simulate detector and sensor electronics performance, correct for projector optics, correct for projector non-uniformity, perform latency compensation, reformat image data and synchronize with the sensor. The UPI is designed to perform these functions as a reconfigurable interface for hardware-in-the-loop (HWIL) testing of infrared and electro-optical (IR/EO) sensor systems. The UPI uses a combination of large-scale Field Programmable Gate Array (FPGA) and PowerPC multi-processor technologies. The UPI supports the interface between the Amherst Systems Real-Time IR/EO Scene Simulation (RISS) Scene Generation System (SGS) and the Unit Under Test (UUT) sensor. The UPI supports both direct injection of image date into the electronics of the sensor or optical projection into the aperture of the sensor. A sensor-specific, Sensor Injection Module (SIM) was developed for the F-22 Missile Launch Detector (MLD), as well as other sensors, for direct injection of the infrared imagery. This paper discuses recent advances in the development and applications of the UPI. Development milestones and current performance benchmarks are presented.
