Infrared Scene Generation, Projection, and Blending with Radio Frequency Energiesfor Hardware-In-The-Loop Simulation Testing

摘要

As missile systems are becoming more complex and the costs associated with live-fire testing are continuing to grow, greater emphasis is being placed on thorough system testing and capability evaluation in the simulation laboratories. To fully test these advanced missile guidance systems the simulation test facilities must present realistic, in-band, backgrounds, targets, and countermeasures to the systems being tested. This paper describes an ongoing tri-service developmental program, Multi-Spectral Scene Generation (MSSG). MSSG includes the generation and projection of complex infrared scenes in a real-time closed-loop sense for testing in hardware-in-the-loop simulation test facilities. The combination of RF and IR energies for the presentation to the seeker/guidance system for simultaneous RF/IR testing is also part of this project. The scene generation must accommodate a 51 2x5 12 array of thermal pixels at a repetition rate of one-hundred Hertz. The infrared scene will be generated with 12 bits of resolution over the temperature and/or emittance values. The interface between the scene generator and the infrared scene projector must transfer and receive this big-gulp of data and pass it on to the seeker/guidance system without creating data artifacts. All projection system non-uniformity's must be removed and the system must be kept in calibration during the testing process.
