Stacking height calculation method of stacker-reclaimer based on radar level indicator

The invention discloses a method for calculating the stacking height of a stacker-reclaimer based on a radar level gauge, which comprises the following steps of: S1, judging the material flow according to the numerical value of a cantilever belt scale, classifying materials with different particle sizes and water contents, collecting the projection length L of inertia throwing of each material on site, and establishing a database; s2, determining the height D1 from the cantilever to the ground according to the formula: D1 = Sin (In1) * B + A; wherein A is the reference height which is the height from the rotation center of the large machine to the track and is actually measured according to a design drawing or on site, B is the length of the cantilever and is actually measured according to the design drawing or on site, and In1 is the pitching angle of the cantilever and is measured in real time through a positioning detection device; s3, the actual height H1 of the material is calculated according to the for
