Assignee: ROBERT BOSCH GMBH
Field: Measurement (Instruments)
Classification: CPC A  G | IPC A  G

Claim 0:
1. A method for ascertaining a plant height of field crops, the method comprising:
ascertaining, using a plant object curve, the plant height using a signal of a radar sensor;
wherein the ascertainment of the plant height includes categorizing reflection objects as plant objects or ground objects,
wherein a distance between the radar sensor and the reflection objects and a relative speed between the reflection objects and the radar sensor are ascertained to categorize the reflection objects,
wherein the plant height is ascertained in that an extrapolation of the plant object curve is carried out, the plant object curve being ascertained based on the distances between the radar sensor and the plant objects, and
wherein ground objects are areas of a ground of a crop area visible to the radar sensor, and wherein plant objects are radar reflections assigned to the field crops in the crop area.
