System Design and Description of Infrared Simulator System BasedOn the Multidimensional Flight Table

摘要

This paper deals with the simulation for the army aviation and missile command at the thermal infrared range scale from2.0 to 4.9μm. The infrared simulator system based on the multidimensional flight table(ISSBMFT) is the significant partof hardware - in - the - loop (HWIL) simulation system for controlling and guiding weapon systems with infrared seekers.It emphasizes on the infrared scene of HWIL simulation experimentation for controlling and guiding weapon andprovides a realistic environment of combat with target/jamming which owns the specific properties of radiant spectrum,entrance angle and target's relative distance variation. Optical system is the basis of the characteristics of the simulator.In the system, three-beam structure is put forward which will make the optical path equal. Through settling attenuators,filters, and polaroids in the beams, which modulates the transmittance, the energy proportion is simulated, so as waveenergy and the entrance angle. So we can simulate one target and two different forms of jamming through variousdistance and conformations. Radiant system and controlling system is the guarantee of the simulation. Calculation ofenergy and the method of controlling is depicted in the article.
