Implementation of adaptive and synthetic-aperture processing schemes in integrated active-passive sonar systems

Proceedings of the IEEE, 1998
Progress in the implementation of state-of-the-art signal processing schemes in sonar systems is limited mainly by the moderate advance made in sonar computing architectures and the lack of operational evaluation of the advanced processing schemes. Until recently, matrix-based processing techniques, such as adaptive and synthetic-aperture processing ...

Sensitivity studies of tapped delay line filters applied to a passive sonar system†

International Journal of Control, 1970
Performance sensitivity of a tapped delay line filter is studied by varying system parameters such as tap coefficients, tap spacings, and the spectra and bandwidth of signal, noise, and directional noises. The optimum filter is designed both with and without the directional noise by using mean-square-error criterion for the case of single and multiple ...

Design of frequency-domain beamforming solution for passive sonar systems in shallow-water environments

Journal of Military Science and Technology
This paper develops the frequency-domain beamforming solution for passive sonar systems operating in shallow-water environments, where acoustic signals are significantly affected by multipath propagation and spatially varying attenuation. The study focuses on optimizing the beamforming configuration by analyzing the influence of key processing ...
