- W1975593961 abstract "Significant progress has been made over the past 3 decades in understanding the acoustic phenomena that affect the operation of high-frequency (i.e., 10 kHz–60 kHz) sonars utilized by systems in the undersea environment such as weapons and autonomous underwater vehicles. The specific underwater acoustic research interests have somewhat paralleled and been motivated by the technology developments for these applications. In the late 1960s and early 1970s, experiments and model development focused on understanding the processes of signal propagation, scattering from the ocean medium (reverberation), and target reflection to predict signal levels for energy detection systems. Recently, systems have evolved to exploit more advancd signal processing concepts that have established a new set of scientific issues. Accordingly, underwater acoustics research has been focused on time/frequency/spatial distribution of energy, temporal, and spatial coherence of signals and background, and a broader scope of complex environments. The increased understanding has been captured in models representing the physical phenomena and rather detailed simulations of the underwater acoustic picture. This paper will review some of the key results in high-frequency underwater acoustics research that have contributed to the current state of knowledge and an indication of the direction for future research." @default.
