“…In this section, we show that, despite such technical problems, the SSR-TRA procedure works well, even using a single TR channel [25,42]. Better results can of course be obtained using a larger number of channels, but are not reported here for brevity.…”

“…The M-ary spread spectrum communication system in ice-covered water based on energy monitoring technology (EMT) adds a spread code selector in the spreading process, which maps the multi-bit binary information stream into one of the pseudo-random sequences for transmission [3] . If the original binary information stream has Figure 1 shows the encoding and decoding process of the M-ary spread spectrum communication in ice-covered water.…”

“…The analysis 11 shows the iterative process involving a time reversal mirror could automatically obtain the optimal incident field to achieve the maximum distinguishability between the target and background in acoustic imaging. The tank experiments 12 are performed with a spherical shell, a small stone, and a complex steel object as targets, and the results indicate the single channel iterative time reversal would provide significant echo enhancement, thus to improve the single-to-noise ratio. Numerical studies 13 demonstrate the iterative time reversal process will gradually lead echoes to converge to a narrowband signal, in which the analysis is mainly based on the case of a rigid sphere in homogeneous half-space.…”
