Claim:
1. A measurement device configured to determine a topology of a bulk material, comprising: an antenna arrangement configured to emit a transmission signal in a primary radiation direction of the antenna arrangement and receive the transmission signal reflected at least on a surface of the bulk material; an echo curve generating unit configured to generate an echo curve, which corresponds to the signal strength of the reflected transmission signal over a distance measurement range of the measurement device, from the reflected transmission signal which is received by the antenna arrangement; a positioning device configured to change the primary radiation direction of the antenna arrangement in such a way that a series of echo curves can be generated at different primary radiation directions; and an evaluation unit configured to determine the topology of the bulk material, wherein the evaluation unit carries out the following steps to determine the topology: wherein the evaluation unit is configured to calculate at least one of a section line of the bulk material or a three-dimensional representation of the surface of the bulk material from data obtained in steps a) to d).
