Recent advances in transducer and computing technology have pushed the concept of continuous active sonar (CAS) or high duty cycle sonar as an area of interest for application to antisubmarine warfare. Unlike conventional pulsed active sonars, CAS pr

Neural Networks are proposed to classify underwater objects from active sonar system data collected for underwater surveillance. The raw signal is processed, transformed in the time-frequency domain and classified (object of interest/clutter). The va

A triplet array has the capability to reduce the port/starboard ambiguity that strongly affects detection and localization in the case of a linear array. When searching for a target near a high clutter area (e.g., a rocky shore near a cliff), this fe

The use of Maritime Unmanned Systems for underwater search requires the development of software tools for embedded real-time environmental decision support to inform robotic decisions. The CMRE Multi-static Tactical Decision Aid and its web-service v

Linear frequency modulated (LFM) continuous active sonar (CAS) waveforms show promise for use in target tracking given that waveforms can be split into sub-waveforms (sub-bands), thereby increasing the target refresh rate. However, reducing the durat

A numerically efficient technique is presented for computing the field radiated or scattered from three-dimensional objects embedded within layered acoustic media. The distance between the receivers and the object of interest is supposed to be large

This work describes the development of continuous active sonar (CAS) processing at CMRE. The software uses subband processing to achieve a faster update rate than is possible with pulsed active sonar (PAS). The software development was based on CMRE'

A sea-floor map can be obtained from sonar data using the supplied sonar system software or one of several public domain or proprietary systems. With any of these solutions, the process of production of a sea-floor map is unnecessarily time consuming
