Description

Technical Field

[0001] This application relates to the technical field of weather radar calibration, and particularly to a calibration service device for a new generation of weather radar. Background Art

[0002] The construction of the new generation of radars in China started in the late 1990s of the 20th century. Currently, there are more than two hundred new generation radars built across the country. The new generation of radars has played an important role in the monitoring and early warning of disastrous weather such as heavy rain, typhoon, hail, and tornado, and remarkable economic and social benefits have been achieved. With the advancement of meteorological modernization, strengthening the scientific evaluation and quality control of various data, and improving the operation quality and efficiency of the comprehensive meteorological observation service have become problems that must be solved in meteorological service operations. This has put forward higher requirements for the reliability of the performance of meteorological equipment, especially large meteorological equipment such as radars, requiring it to ensure sufficient detection accuracy and stable and reliable system performance.

[0003] However, during the actual operation of the radar, its detection results often change due to changes in the external environment and the characteristics of the system itself. These changes will directly affect the accuracy of the observation data of the new generation of radars, bringing difficulties and losses to the normal business observation, networking mosaicking, data sharing, etc. of the radars. Conducting calibration on the new generation of radars is an important means to solve the changes in the characteristics of the radar system itself. Currently, the Observation Department of the China Meteorological Administration has incorporated the calibration work of the new generation of radars into the key business work of radar support. Therefore, in radar support, it is necessary to regularly and irregularly conduct calibration tests on the working parameters of the radar system itself and process the unqualified calibration results.

[0004] Currently, there are many items for calibrating radar data. For example, calibrating the horizontal degree of the radar antenna pedestal, calibrating the loss of the radar transceiver path, calibrating the control accuracy of the servo system, etc. In order to complete the calibration of different items, different calibration devices are required. For example, in order to complete the calibration of the radar antenna pedestal, a leveling device needs to be set up. There are many devices for leveling the radar antenna pedestal. For example, a radar leveling device disclosed in a Chinese patent with the publication number CN110927701A includes a base, a bracket for installing the radar and having a gap with the base, and an elastic support assembly provided between the base and the bracket; a first adjustment screw, a second adjustment screw, and a third adjustment screw are provided between the base and the bracket; the bracket is installed on the base through the first adjustment screw, the second adjustment screw, and the third adjustment screw; the first adjustment screw, the second adjustment screw, and the third adjustment screw are located at the three corners of the same triangle. Since there is a gap between the bracket and the base and elastic support is realized through the elastic support assembly, the gap between the base and the bracket at various places can be changed by rotating the above three screws, thereby changing the attitude of the radar, that is, realizing four-way adjustment of forward tilt, backward tilt, left deviation, and right deviation until the usage requirements of robots and other mechanical equipment are met.

[0005] Although the above leveling device can calibrate the levelness of the radar antenna base, when using it to level the base, it is necessary for the staff to rotate multiple screws one by one. Since the leveling device is installed in the gap between the radar base and the radar, it is not conducive to the staff to complete the above operations. Summary of the Invention
