heat signature
Infrared body trace
The pattern of infrared radiation emitted by an object, revealing its presence and temperature.
Military and law enforcement use thermal imaging to detect heat signatures of people, vehicles, or equipment: The helicopter's sensors picked up a heat signature in the woods.
Wildlife researchers track animals the same way.
Anything producing heat—engines, bodies, electronics—has a detectable heat signature.
