A heat sensing system and method for dynamic heat sensing may be implemented in a flight vehicle having a main antenna configured for sending and/or receipt of signals. The system includes an auxiliary antenna system that is arranged within a radome of the flight vehicle for detecting temperatures around the exterior surface of the radome. The auxiliary antenna is configured for receiving and measuring infrared or optical energy. Using the measured energy, the system is configured to determine whether the detected temperature exceeds a predetermined temperature and rotating the vehicle to equalize heat around the vehicle when the current temperature exceeds the predetermined temperature.
