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.

21. A method for selecting a spread sequence, comprising:
-
storing a plurality of spread sequences; measuring an elevation of a vehicle; generating elevation data indicative of the measured elevation of the vehicle; and selecting at least one spread sequence of the plurality of spread sequences based on the elevation data, wherein the selected spread sequence is a spread sequence different from a spread sequence that is selectable by a vehicle travelling on an elevation different from the elevation of the vehicle. - View Dependent Claims (22)
