On synthetic aperture sonar [PDF]
The Journal of the Acoustical Society of America, 1988 Synthetic aperture technology is used in airborne radar or on satellites like SEASAT to obtain high-resolution pictures of the Earth's surface. On the other hand, in the field of underwater acoustics, the effectiveness of synthetic aperture side-looking sonar has long been predicted.

The Topology of Circular Synthetic Aperture Sonar Targets
CoRR, 2022 This report presents a connection between the physical acoustics of an object and the topology of the space of echoes resulting from a circular synthetic aperture sonar (CSAS) collection of that object. A simple theoretical model is developed that yields a precise, yet qualitative, description of the space of echoes. This theoretical model is validated

Frequency‐domain multireceiver synthetic aperture sonar imagery with Chebyshev polynomials
Electronics Letters, 2022 Based on Chebyshev polynomials, the two‐way slant range is first approximated by the fourth‐order polynomial approximation. With the series reversion method, the point target reference spectrum (PTRS) which is further used for the development of imaging ...

A Comparison of PCA and LBF Based Multireceiver SAS Imaging Algorithms
IEEE Access, 2023 Multireceiver synthetic aperture sonar (SAS) is a useful tool to provide high-resolution images. The most important step lies in developments of multireceiver synthetic aperture image formation processors, which uses the sonar echoed signal as the input.
