[0039] The good sealing performance of the radome affects the flow of air inside and outside the radome, resulting in poor heat dissipation performance of the antenna system. Radar generates a large amount of heat during operation. The radome also receives solar heat radiation and absorbs radar waves, which in turn increases the temperature of the radome, the ambient temperature, and the temperature of the electrical equipment, affecting the accuracy and efficiency of the antenna equipment. The present invention provides an air inlet on each side of the support wall, facing the center of the sphere of the radome, and an air outlet on each side of the radome. A temperature sensor is used to detect the temperature inside the weather hood in real time and wirelessly transmits the temperature data to a detection device. The processor in the detection device transmits the received data to a comparator, which compares the received data with preset data. If the temperature exceeds a preset range, an alarm unit is used to issue an alarm. An air supply device is used to supply air to the air inlet for processing, and the air is discharged through the air outlet, achieving heat exchange and reducing the temperature inside the weather hood. This achieves intelligent and automated temperature management inside the weather hood and facilitates timely detection of abnormalities.
