ABSTRACT:
A pulse sequence is produced by repeatedly selecting individual pulse trains at random from a set thereof, each pulse train meeting predetermined autocorrelation constraints and the pulse trains collectively meeting predetermined cross-correlation constraints. The pulse trains are preferably separated by gaps of random length. At least some pulse trains may be time-reverse replicas of others. The resulting sequences are particularly suitable for obstacle detection in multiuser environments.
