Two novel chaotic modulations are proposed to improve the security of underwater acoustic communications.
- class="label">•
An automatic modulation (AMC) system is designed to identify the modulation type and order of digital modulation signals.
- class="label">•
The proposed chaotic modulations have much lower probability of availability than conventional digital modulations.

The performance of chaotic modulations in actual underwater acoustic communications was verified by an experiment.
