Application of de Bruijn sequences in automotive radar systems: Preliminary evaluations

This paper presents preliminary evaluations about the possible adoption of de Bruijn sequences as an alternative to more conventional spreading codes in direct sequence spread spectrum automotive radars. The main advantage in using binary de Bruijn sequences relies in their huge cardinality with respect to any other family of binary sequences, at a parity of length. A huge cardinality represents a valuable element in a crowded environment like the automotive context, in order to provide many vehicles with different radar signatures. Correlation properties of de Bruijn sequences are investigated and compared to classical solutions.
