Modern threats are evolving to use multi-spectral sensor suites, including radar and infrared. It is therefore essential to be able to measure and model an asset’s infrared signature in order to determine its vulnerability.
Field Measurements
The field measurements are carried out with current generation thermal radiometers. Additional information is gathered such as the meteorological conditions and the distance between the target and the radiometers.
Modelling
The corrected data from the field measurements are combined with a solid model of the target to generate a three-dimensional radiometric model of the target.
Data Analysis
The data analysis process corrects the measured data for errors caused by the atmospheric transmittance. The atmospheric transmittance is calculated using the MODTRAN code.
Signature Prediction
The target’s radiometric model can be used in a variety of scenarios to predict the infrared signature.
