Based on the interference spectrogram in the element–frequency domain using the data
measured by the horizontal linear array, the source range can be estimated through the …

The element–frequency acoustic intensity of a horizontal line array with a sufficient aperture
exhibits interference striation patterns, which can be used for source range estimation …

Thanks to lowering costs, sensors of all kinds have increasingly been used in a wide variety
of disciplines and fields, facilitating the rapid development of new technologies and …

Due to the dispersion of normal modes in shallow water, there exist regular striations on the
interference spectrogram in space-frequency domain. Based on the range-frequency …

The ray-based blind deconvolution algorithm can provide an estimate of the channel
impulse responses (CIRs) between a shipping source of opportunity and the elements of a …

浅海低频声场呈稳定而显著的干涉特征, 并蕴含声源状态和波导特性等信息.
本文研究运动目标辐射声场干涉结构的简化映射以及映射域能量分布对目标运动状态的指示 …

The low-order normal modes with small grazing angles (SGA) often control long-range
sound field characteristics in shallow water. The SGA reflection loss from a half-space low …

Attenuation is the most difficult seafloor acoustic property to get, particularly at low to mid
frequencies. For low velocity bottoms (LVB), it becomes even more challenging, due to its …

Shipping activities are diverse, extend almost globally, and have increased in intensity over
the past half‐century. Motorized ships radiate underwater noise through numerous and …

The waveguide invariant β is typically discussed in terms of either a range-independent
environment or a range-dependent environment under the adiabatic approximation, with few …
