DOI: 10.1080/10584587.2020.1728798
Abstract: Abstract In order to improve the detection performance of active sonar and make up for the shortcomings of pulsed active sonar (PAS), linear frequency-modulated continuous wave (LFMCW) was applied in continuous active sonar (CAS). The… read more here.

DOI: 10.1109/joe.2016.2540744
Abstract: The question of localizing a target with multistatic active sonar is reexamined from the perspective of finding a peak in a probability distribution function. The probability distribution function is constructed using straightforward Bayesian principles. Both… read more here.

DOI: 10.1121/1.5036498
Abstract: Continuous Active SONAR (CAS) systems allow duty cycles up to 100% and so lower target association errors are possible as compared to Pulse Active Sonar (PAS). Large time-bandwidth product Linear Frequency Modulated (LFM) signals are… read more here.

DOI: 10.1121/1.5068266
Abstract: Multi-channel passive acoustic data were collected from bottom-mounted hydrophones off the coast of Kauai, HI at the U.S. Navy Pacific Missile Range Facility’s instrumented range. In February 2017, data were recorded during the Submarine Command… read more here.
