Method of identifying an object signature in an environment and system for identifying an object signature in an environment

A system for identifying an object signature in an environment, comprising:

• a detection unit configured to acquire infrared information from the environment to obtain an infrared wavelength spectrum associated with the environment;
• a filtering unit configured to select three wavelength bands of the infrared wavelength spectrum;
• and
• a processing unit configured to detect a presence of the three wavelength bands of the infrared wavelength spectrum in the environment by filtering the selected three wavelength bands using the filtering unit;
• wherein the processing unit is configured to determine an intensity indicator for the three selected wavelength bands;
• and
• wherein the processing unit is configured to classify the object signature based on the determined intensity indicator to identify the object signature, and
• wherein for classifying the object signature, the processing unit is configured to define a three-dimensional space, each dimension of the three-dimensional space defining an intensity amount for a respective one of the three detected wavelength bands.
