Aiming at problem of large nonlinear error of characteristic curve of capacitive sensor applied to measurement of rainfall
least square curve fitting method and radial basis function( RBF) neural network are used to fit output characteristic curve. The results show that the RBF neural network model has stronger nonlinear mapping ability
and its fitting precision is significantly higher than that of the least square polynomial model.
