For a radar based True-Speed-Over-Ground measurement system an interpolation based precision improvement is presented. The system is based on the cross-correlation of two radar receive signals. The theoretical basics of the interpolation are thoroughly introduced and its limits are determined for the general case and for a specific hardware. Measurement results including the interpolation are presented and compared to the former implementation.
