In this paper, we discuss the PAS (Pulse Active Sonar) and CAS (Continuous Active Sonar) strategies for target detection and tracking. CAS system potentially offer several advantages over traditional PAS systems, mainly in term of probability of detection and/or tracking. With a continuous insonification of the target, CAS can track continuously limiting the data association error inherent to PAS system. Recent works in MIMO (Multiple Input Multiple Output) radar and sonar have bring new solutions for the orthogonal waveform design problem. We present here a modified CDMA (Code Division Multiple Access) waveform adapted to sonar constraints. Using such waveforms offers a mid-way solution between PAS and CAS allowing the user to decrease the PRI (Pulse Repetition Interval) and then increasing the hits on target but not at the cost of sacrificing the full bandwidth.
