Practical High-Frequency Sonar for Intruder Detection in Very Shallow Environments

An active high-frequency sonar system has been identified that is appropriate for detection and classification of human-sized targets in very shallow littoral environments. The system uses technology that is currently in use in fisheries acoustics. This technology has been optimized over the last few decades to provide a robust, cost-effective solution for detection of biological targets in cluttered environments. These systems have been proven over many years of use in fish detection applications, and as such are potentially suitable for deployment in security applications in the near future. In this presentation we will discuss important characteristics of the technology, as well as steps that are being taken towards its adaptation for security use
