Abstract
The invention relates to a method for object classification which comprises the following steps for providing an ellipti-cally or circularly polarized transmission signal which is transmitted to the object to be classified: generating a first radar image from the copolarly polarized reflection signal and generating a second radar image from the cross-polarized reflection signal and comparing the first radar image with the second radar image.

A method for object classification of an object to be classified, the method comprising:
- providing an elliptically or circularly polarized transmission signal, which is transmitted onto the object to be classified from a transmitter;
- evaluating a first minima of a cross-polar component of a first reception signal when the object is at a first distance from the transmitter, wherein the cross-polar component is cross-polar in relation to the transmission signal;
- evaluating a second minima of a cross-polar component of a second reception signal when the object is at a second distance from the transmitter, wherein the cross-polar component is cross-polar in relation to the transmission signal;
- and
- determining the height of the object based on the first minima and the second minima.
A device for establishing an object classification of an object to be classified, the device comprising:
- means for providing an elliptically or circularly polarized transmission signal, which is transmitted onto the object to be classified;
- means for evaluating a first minima of a cross-polar component of a first reception signal when the object is at a first distance from the means for providing the elliptically or circularly polarized transmission signal, wherein the cross-polar component is cross-polar in relation to the transmission signal;
- means for evaluating a second minima of a cross-polar component of a second reception signal when the object is at a second distance from the means for providing the elliptically or circularly polarized transmission signal, wherein the cross-polar component is cross-polar in relation to the transmission signal;
- and
- means for determining the height of the object based on the first minima and the second minima.
