Abstract
A method for transmitting a spread spectrum radar signal stores a plurality of spread sequences. Further, an elevation of a vehicle is measured by the method. Based on the measured elevation of the vehicle, the method selects at least one spread sequence of the plurality of spread sequences, and transmits a spread spectrum radar signal based on the selected at least one spread sequence. Additionally, the method may measure a travel direction of the vehicle, and then select at least one spread sequence based on the measured elevation of the vehicle and the measured travel direction of the vehicle.
