A method for generating a compact representation of radar data, the method comprising:
- determining at least one data peak within a multi-dimensional representation of radar data, wherein the multi-dimensional representation of the radar data comprises a first dimension for a distance, a second dimension for a velocity, and a third dimension for a receive channel;
- selecting a first limited neighborhood around the at least one data peak, wherein the selected first limited neighborhood includes data bins with different positions in the third dimension and identical positions in the first and the second dimensions of the multi-dimensional representation of the radar data;
- compressing first radar data samples of the multi-dimensional representation located within the first limited neighborhood around the at least one data peak to generate the compact representation of radar data;
- and
- transmitting the compressed first radar data samples as the compact representation of the radar data.
A method for generating a compact representation of radar data based on a multi-dimensional representation of the radar data in which a receive channel dimension represents a receive channel, the method comprising:
- selecting data bins within the multi-dimensional representation of the radar data, the selected data bins having different positions in the receive channel dimension and identical positions in remaining dimensions of the multi-dimensional representation of the radar data, the remaining dimensions being different from the receive channel dimension;
- compressing neighboring radar data samples of the selected data bins by representing an amplitude component of the neighboring radar data samples of the selected data bins with a reduced number of bits;
- and
- transmitting the compressed neighboring radar data samples as the compact representation of the radar data.
A radar device, comprising:
- radar data generation circuitry configured to provide a multi-dimensional representation of radar data, wherein the multi-dimensional representation of the radar data comprises a first dimension for a distance, a second dimension for a velocity, and a third dimension for a receive channel;
- and
- a radar data processor configured to determine at least one data peak within the multi-dimensional representation of the radar data, and compress radar data samples of the multi-dimensional representation of the radar data located within a limited neighborhood around the at least one data peak to generate a compact representation of the radar data.
A radar data processing circuit, comprising:
- an input interface configured to receive a compact representation of radar data, the compact representation of the radar data comprising compressed radar data samples taken from a limited neighborhood around at least one data peak;
- and
- a processor configured to estimate object characteristics based on the compact representation of the radar data.
