Zusammenfassung:	The present inventive concept relates to a method (20) for determining a flow metric for a flow of granular particles, the method (20) comprising: performing (S200), using a radar sensor (100), a plurality of radar measurements distributed over a measurement time period comprising: transmitting (S202) radar pulses through the flow and in a direction across the flow, receiving (S204) reflected signals, and sampling (S206) the reflected signals; estimating (S208), using a radar signal processor (120) and based on the samples, a variation over time of an amplitude of the reflected signals; and determining (S210), using the radar signal processor (120), the flow metric based on the estimated variation, wherein the flow metric is indicative of a flow rate of the flow of granular particles.
