Infrared Signature Prediction

IDS Prediction services for infrared (IR) signatures cover IR signature assessment and reduction, IR imaging and thermal analysis.

IR signature assessment and reduction

Infrared signature defines the appearance of objects to infrared sensors. In the aeronautical field, this signature of aircraft platforms depends on many factors, including the shape and size of the object, surface temperature and materials, engine exhaust plume temperature and gas composition, reflection of external sources from the object's surface, the background against which it is viewed as well as the waveband of the detecting sensor.

IDS Aeronautical Division’s expertise in this field ensures highly professional and reliable consulting services for IR assessment and reduction. This capability is becoming increasingly important as more sensitive signature detection systems are being developed.

IR imaging

IR images can be exploited to highlight hot spots on the aircraft and then mitigate them, in order to reduce the global IR signature.

IR images can also be exploited to identify and classify the target, exploiting the target’s hot spots as a “fingerprint”.

Thermal analysis

Thermal data are the basic input for IR signature evaluation. The thermal field around an aircraft is affected by air friction and compressibility heating, heat conduction through surfaces, natural and forced convection, sun glint and irradiation, engine exhaust plume impingement and irradiation on aircraft structures, etc.

IDS Aeronautical Division exploits accurate CFD (Computational Fluid Dynamics) software to solve the complex thermal field that develops around an aircraft.
