heat signatures
Thermal radiation patterns
Heat signatures are the patterns of infrared radiation emitted by objects, which vary based on temperature.
Military and surveillance systems detect heat signatures to locate people, vehicles, or equipment—especially at night or through obscuring conditions: The drone picked up heat signatures in the building.
Wildlife researchers use thermal imaging to track animals by their heat signatures.
