Problems solved by technology

[0003] In the past, the large-range radar basically had a relatively large horn device, which would cause the radar water level and the blind area to be larger
The existing radar water level gauge generally uses a scanning frequency below 60GHZ, and the bandwidth is also small, both of which lead to low accuracy of the radar water level gauge
The existing radar water level gauge has too high power consumption, too large volume, low accuracy and too large blind area

Description

technical field [0001] Embodiments of the present invention relate to radar water level measurement technology, in particular to a radar water level measurement device and a radar water level measurement control system. Background technique [0002] With the development of hydrological monitoring technology, non-contact water level measurement has been widely used for its fast, safe, high precision and wide application. The radar water level gauge adopts a non-contact water level measurement method, which is not affected by debris in the water and has high measurement accuracy. [0003] In the past, the large-range radar basically had a relatively large horn device, which would lead to a larger blind area of ​​the radar water level. The scanning frequency of the existing radar water level gauge is generally below 60GHZ, and the bandwidth is also small, both of which cause the accuracy of the radar water level gauge to be low. The radar water level gauge in the prior art ha...
