Embodiment Construction
[0030] The present invention is based on a fixed-point multi-point flow measurement method for a river section based on a radar current meter fixedly installed above the river (i.e. a fixed point). The installation position of the radar current meter can be flexibly set, for example, it can be installed In the center, on the edge of the river, or at a certain position on the river. The radar current meter can adjust its horizontal orientation by horizontal rotation (horizontal orientation refers to the direction the radar current meter is facing based on the rotation in the horizontal plane), so as to measure the flow of multiple measurement points on the same river section. In practice, the water levels of the multiple measurement points on the same river section may be different, and the radar current meter can adjust the vertical inclination based on the water level change (the vertical inclination refers to the detection direction of the radar current meter and its own vert...
