MESSEINRICHTUNG AN EINER LANDWIRTSCHAFTLICHEN MASCHINE
摘要
At least one electromagnetic sensor e.g. radar sensor (46,48,50) is operably mounted in the agricultural machine (20) for emitting a signal that can penetrate field vegetation (35). The sensor receives the reflected signal from the ground in non-contact state to determine the distance between the front attachment of the machine and the ground surface (36). An Independent claim is also included for a non-contact determination method of distance between machine and surface.
