Estimation of the leaf area by means of a mobile radar within a cultivated plot

摘要

The invention relates to a method for determining the leaf area of a cultivated plot, by means of a mobile radar unit (1) positioned at the height of the crops in the plot, said radar unit being in communication with a processing unit. configured to implement steps of: - E1) emission of continuous waves modulated in frequency in the direction of the field by means of the radar unit, the radar unit (1) illuminating a determined zone (z) of the field ; - E2) obtaining at least one radar image of the cultivated plot (20) by means of the radar unit (1), said image consisting of voxels or pixels each comprising a level quantifying a quantity of waves reflected by the crops (5) of the plot; - E3) processing of the acquired image to obtain at least one parameter indicative of the leaf area of the plot.
