Description

Technical Field

[0001] The present invention relates to the field of radar technology, and in particular to an active ventilation and cooling system and method for a radar antenna cover. Background Art

[0002] With the continuous development of modern radar technology, the performance and power of radar antennas are constantly improving, especially large radar antennas such as multi-target tracking and identification radar antennas and early anti-missile warning radar antennas are becoming more and more widely used. However, the transmission power of these high-performance radar antennas is very large. The continuous wave transmission power of a single antenna can reach thousands of watts, and they usually work all day long. As an important protective device for radar antennas, the main function of the radar antenna cover is to achieve physical isolation between the radar and the natural environment, prevent the environment from affecting and interfering with the working state of the radar antenna, and extend the service life of the radar. However, due to the small distance between the radar antenna and the antenna cover, the spatial attenuation of high-power microwaves is small, and they directly enter the interior of the antenna cover, increasing the power density inside the antenna cover. In addition, the thermal conductivity of the radar antenna cover material itself is poor, and heat continues to accumulate in the antenna cover, causing the temperature to gradually rise.

[0003] Most existing radar antenna covers are passive ventilation devices, and their ventilation and cooling capabilities are greatly affected by the natural wind force and wind direction, and cannot meet the heat dissipation requirements of high-power radar antennas. The increase in temperature inside the antenna cover not only damages the material and structure of the radar antenna cover, affecting its service life, but is also more likely to cause thermal overload of the radar antenna, which in turn affects the normal operation of the radar antenna and brings serious consequences. In addition, existing radar antenna covers are prone to water or snow accumulation in rainy and snowy weather, affecting the radiation and reception of electromagnetic waves, causing the radar to fail to work properly. At the same time, the high temperature inside the antenna cover can easily cause damage to the equipment and reduce reliability, and even cause the radar system to shut down due to high temperature in extreme cases.

[0004] In order to effectively solve the above problems, the prior art has proposed a variety of improvement schemes for radar antenna covers, such as adopting an active ventilation and cooling system, by setting vents on the top of the antenna cover, setting multiple active ventilation and cooling devices on the bottom, and equipping with a fan controller and an automatic temperature controller, to achieve real-time monitoring of the temperature inside the antenna cover and forced circulation ventilation, significantly improving the cooling capacity of the antenna cover. However, these schemes still have certain shortcomings in practice, such as the complexity of the pre-buried pipelines, which affects the molding effect of the cover body and its wave transmission performance, the low degree of automation, and the failure to achieve timed detection and control of the temperature. In order to further improve the heat dissipation performance of the radar antenna cover and solve the problem of poor heat dissipation in high temperature environments, a new active ventilation and cooling system for the radar antenna cover is urgently needed to ensure the efficient operation and heat dissipation performance of the radar antenna in various environments.

[0005] There are already some invention patents to solve the problem of poor heat dissipation of radar antenna covers in high temperature environments. For example: CN209561597U discloses an active ventilation and cooling system for a radar antenna cover. The system relates to the field of active ventilation and cooling of radar antenna covers. The antenna cover is designed to have a cavity-opening hemispherical shape, and a top vent is provided at the top of the antenna cover. A plurality of active ventilation and cooling devices are provided along the circumferential outer wall at the bottom of the antenna cover. These devices are arranged symmetrically in pairs with the center of the bottom of the antenna cover, and a fan controller is provided on the bottom surface of the antenna cover to control the start and stop of the active ventilation and cooling device. This design is suitable for cooling the radar antenna when it is working. However, the problem that still exists in this patent is that it is necessary to further improve the ventilation and cooling efficiency of the system and reduce energy consumption to meet the needs of more efficient heat dissipation.

[0006] CN107069209A discloses a radar antenna cover with ventilation and cooling functions. The invention has air supply ports and air outlets on the antenna cover, a blower is arranged in the air supply ports, and an air cooling device is arranged on the antenna array surface of the radar. The two air supply ports are symmetrically offset from the front of the radar antenna array surface, and the center point of the line connecting the center points of the two air supply ports, the center of the radar antenna cover, and the center of the air outlet are collinear. This design makes full use of natural cold sources to reduce the temperature inside the cover and ensure the normal operation of the radar. However, the problem that still exists in this patent is that it is necessary to further optimize the layout and size of the air supply ports and air outlets to improve the ventilation and cooling effect, and it is necessary to monitor the temperature inside the cover in real time so as to adjust the air supply volume and air cooling intensity according to actual conditions to achieve more accurate temperature control.

The hose is flexible and can adapt to different installation angles and distances while ensuring smooth airflow. The dust filter 33 is usually installed at the air inlet of the fan 35 to filter out dust and impurities in the air. The filter should be cleaned or replaced regularly to maintain its filtering effect. The protective net 32 ​​is installed at the air outlet or air inlet of the fan 35 to prevent foreign objects from entering the fan 35 and causing damage. The protective net 32 ​​should have sufficient strength and density to block larger objects and insects. The fixing bracket 36 is used to fix the ventilation holes on the antenna cover 2 and ensure its accurate position.

[0037] If the device needs to be installed on the radome 2, the fixing bracket 36 should be able to be firmly fixed on the radome 2 and support the ventilation holes and related connecting parts.

[0038] The wind direction adjustment tube 34 is used to adjust the air outlet direction of the fan 35 so as to better control the distribution of the airflow. The adjustment tube can be installed at the air outlet of the fan 35 and adjust the air outlet direction by rotating or moving.

[0055] Equipment status inside the antenna cover: including equipment power, operating time, fault records, etc.

[0056] Data preprocessing can be used to clean the data: remove outliers, duplicate values, and missing values. And feature engineering: extract features that affect temperature control, such as time (hour, date, season), weather type (sunny, rainy, snowy, etc.), equipment load, etc.

[0057] Finally, normalization / standardization is performed to ensure that different features have similar weights in model training.
