In continuous marine monitoring a further challenge is related to the computational complexity of the signal processing pipeline\u2014due to energy constraints, in off-shore monitoring platforms algorithms should operate in real time with limited power consumption. In this paper, we present an innovative method that allows to accurately detect and track underwater moving targets from the reflections of an active acoustic emitter. Our system is based on a computationally- and energy-efficient pre-processing stage carried out using a deep convolutional denoising autoencoder (CDA), whose output is then fed to a probabilistic tracking method based on the Viterbi algorithm. The CDA is trained on a large database of more than 20,000 reflection patterns collected during 50 designated sea experiments. System performance is then evaluated on a controlled dataset, for which ground truth information is known, as well as on recordings collected during different sea experiments. Results show that, compared to the benchmark, our method achieves a favorable trade-off between detection and false alarm rate, as well as improved tracking accuracy.<\/jats:p>","DOI":"10.3390\/s20102945","type":"journal-article","created":{"date-parts":[[2020,5,22]],"date-time":"2020-05-22T10:18:18Z","timestamp":1590142698000},"page":"2945","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Combining Denoising Autoencoders and Dynamic Programming for Acoustic Detection and Tracking of Underwater Moving Targets"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7062-4861","authenticated-orcid":false,"given":"Alberto","family":"Testolin","sequence":"first","affiliation":[{"name":"Department of Information Engineering, University of Padova, Via Gradenigo 6\/B, 35141 Padova, Italy"},{"name":"Department of General Psychology, University of Padova, Via Venezia 8, 35141 Padova, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2430-7061","authenticated-orcid":false,"given":"Roee","family":"Diamant","sequence":"additional","affiliation":[{"name":"Hatter Department of Marine Technologies, University of Haifa, Haifa 3498838, Israel"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"919","DOI":"10.1006\/jmsc.2000.0579","article-title":"Acoustic estimation of longline tuna abundance","volume":"57","author":"Bertrand","year":"2000","journal-title":"ICES J.
