Abstract :
One novel method to construct extended Costas sequences with ideal auto- and cross-ambiguity functions is proposed. By combining the Golomb rulers with frequency hop sequences, extended Costas sequences with ideal ambiguity functions can be obtained without computer exhaustive search. This method can also eliminate the disadvantage of large auto-ambiguity functions for linear congruence sequences in radar and sonar applications.
