A device and method for determining a classification of an object. A radar spectrum which includes radar reflections is determined as a function of sensor data from a radar sensor. Embeddings of sections from the radar spectrum which include at least one radar reflection are determined and each is assigned to a node of a first graph. Edges are determined as a function of pairwise distances between the embeddings which are assigned to the nodes. For each edge, a feature for the edge is determined as a function of the embeddings of two nodes which are connected to one another by the edge. For each node, a feature for the node is determined as a function of the features for the edges which connect the node to another node. A characteristic quantity is provided for each radar reflection as a function of the sensor data.
