Description

technical field [0001] The invention relates to an X-band weather radar, in particular to a lightweight integrated X-band weather radar structure. Background technique [0002] With its unique ability to detect small-scale meteorological systems and its operating wavelength characteristics, X-band meteorological radar plays a unique role in monitoring small-scale strong convective weather such as small-scale precipitation, hail clouds, tornadoes, and cyclones. It is mainly used for artificially influencing the weather, meteorological disaster prevention and mitigation, emergency meteorological support and scientific experiments.

AI Technical Summary

Problems solved by technology

[0003] However, the current domestic traditional X-band weather radar structure design is relatively simple, and there are still the following deficiencies:

[0004] 1. The turntable is complex, heavy, and consumes a lot of power: the structure of the traditional X-band weather radar considers environmental factors such as wind resistance and waterproof, and increases the thickness of the metal casting, which leads to an increase in the weight of the whole machine and the increase in the servo drive power. Power consumption rises

[0005] 2. Complicated maintenance: In the maintenance of traditional X-band weather radar, on the one hand, it needs to be disassembled sequentially from the outside to the inside to replace the faulty parts; on the other hand, the degree of modularization is not high, and when a fault occurs, it needs to be checked and tested at the device level on site

[0006] 3. Single operation mode: the traditional X-band weather radar operation mode is limited by application scenarios and structural design, and can only achieve a pitch angle of 0-90° rotation

Because the structure is heavier and the center of gravity is biased, it will cause a reverse impact on the pitch gear when turning over the top, causing the gear to lose step, and causing an angle error to the servo motor

[0007] Radar over-the-top scanning can make the radar quickly turn to the opposite direction, shorten the detection time, thereby increasing the early warning and forecast time for rapidly changing disastrous weather. In addition, in aviation meteorology, it is necessary to carry out forecast and early warning on the runway and the extension lines on both sides, so the traditional X Band weather radar does not meet the needs of aviation meteorology, scientific research and other fields
