Using blankets or similar materials to hide the heat signature of a tank and prevent thermal imaging from detecting it is highly unlikely to be effective. Thermal imaging technology is designed to detect differences in heat radiation, and blankets alone are generally not sufficient to completely mask the heat signature of an object like a tank.
Thermal imaging works by detecting the infrared radiation emitted by objects based on their temperature. Objects at different temperatures emit different amounts of infrared radiation, and thermal imaging cameras can detect these variations. Blankets, even if they are good insulators, do not completely eliminate the heat emitted by an object. They may reduce the rate of heat transfer to some extent but are unlikely to eliminate the heat signature entirely.
Additionally, tanks generate heat from various sources, including the engine, exhaust, and other components. These heat sources are typically significant and would be challenging to completely mask or hide with blankets alone.
It's worth noting that there are advanced techniques and technologies that can potentially reduce an object's heat signature, such as thermal insulation, active cooling systems, or special materials designed to absorb or redirect infrared radiation. However, these techniques are typically more complex and are not easily achieved with simple blankets.
In summary, while blankets may offer some degree of insulation, they are unlikely to be effective in completely hiding the heat signature of a tank from thermal imaging technology. Thermal imaging systems are specifically designed to detect heat differences and are capable of identifying objects based on their thermal emissions, even if attempts are made to mask or reduce the heat signature.
