| Popis: | A framework for designing covert sonar waveform and assessment of its steganographic security for sonar applications is presented, based on a model for the underwater ambient acoustic environment the waveform is intended to hide under. Adopting the lessons from the steganography literature, steganographic security is measured not by evaluating performance against potential intercept detectors, but by measuring the Kullback-Leibler divergence between the background model and the model of the background perturbed by the candidate waveform. A modeling method using symbolic time series analysis with phase space representation allows for capturing the time-evolving aspect of the ambient environment on the timescale of sonar applications of interest such as tracking. |
