In the future, modern airliners will use enhanced-synthesic vision systems (ESVS) to improve aeronautical
operations in bad weather conditions. Before ESVS are effectively found aboard airliners, one must develop a
multisensor flight simulator capable of synthetizing, in real time, images corresponding to a variety of imaging
modalities. We present a real-time simulator called ARIS (Airborne Radar and Infrared Simulator) which is
capable of generating two such imaging modalities: a forward-looking infrared (FLIR) and a millimeter-wave
radar (MMWR) imaging system. The proposed simulator is modular sothat additional imaging modalities can
be added. Example of images generated by the simulator are shown.
We describe a multisensor (or multimodal)
flight simulator (FS), which is currently capable of generating forwardlooking
infrared (FLIR) imagery and is designed in such a way that modules can easily be added to produce
other types of imagery such as for millimeter-wave radar (MMWR). Such sensors are the basis for the enhanced
vision systems (EVS) that are currently considered for installation aboard commercial and military aircraft to
enhance the safety of operation in poor-visibility weather or even in zero-visibility weather. The main source
of information for our simulator is an airport database, which is, in part, intended for driving synthetic vision
systems (SVS). We describe the architecture of the simulator and of its FLIR module. Preliminary simulation
examples are also shown.
