Dolphin-Inspired Target Detection for Sonar and Radar
Gas bubbles in the ocean are produced by breaking waves, rainfall, methane seeps, exsolution, and a range of biological processes including decomposition, photosynthesis, respiration and digestion. However one biological process that produces particularly dense clouds of large bubbles, is bubble netting. This is practiced by several species of cetacean. Given their propensity to use acoustics, ...
متن کاملTarget Detection in Clutter for Sonar Imagery
This proposal is a direct response to Challenge 22: Target detection in clutter. The Oceans Systems laboratory have a large experience in Target Detection and Classification in high resolution sonar imagery using a variety of techniques based on target responses and highlight shadow pairs[1,2,3]. Experiments on real scenarios show that these techniques work well in benign environments (flat and...
متن کاملClutter Removal in Sonar Image Target Tracking Using PHD Filter
In this paper we have presented a new procedure for sonar image target tracking using PHD filter besides K-means algorithm in high density clutter environment. We have presented K-means as data clustering technique in this paper to estimate the location of targets. Sonar images target tracking is a very good sample of high clutter environment. As can be seen, PHD filter because of its special f...
متن کاملDolphin sonar--modelling a new receiver concept.
Observations suggest that dolphin sonars function well in the very shallow, reverberant, near-shore region of the ocean, and significantly out-perform man-made systems under such conditions. The echolocation characteristics of many small cetaceans have been measured directly and the high performance of biosonar systems is not in question, but explanations for their resolution, target detection,...
متن کاملSonar Target Classification with Sonar Fingerprint
To recognize underwater target precisely is always a hot potato to navies due to the complicated watery environment. It’s different from the aerial circumstance. There is much more interfere under the sea. Sonar is the most efficient way to detect underwater world at present time. In this paper, a geneticbased classifier system is designed which recognizes targets by sonar fingerprints. This me...
