Abstract

Представлен новый способ построения акустических изображений, который обеспечивает получение изображений с сниженным шумом реверберации, получение изображений параметров нелинейного рассеяния и распространения от объекта, а также способы определения коррекций для аберраций волнового фронта, вызванных пространственными изменениями акустической скорости распространения. Эти способы нашли применение в различных областях, таких как акустические изображения геологических структур, получение изображений подводных объектов с помощью гидролокации, а также в получении медицинских ультразвуковых изображений. Способы основаны на обработке принятых сигналов от излученных групп акустических импульсов в двухполосном частотном диапазоне с перекрывающимися высокочастотными и низкочастотными импульсами. Высокочастотный импульс используется для реконструкции изображения, тогда как низкочастотный импульс используется для управления свойствами высокочастотного рассеяния и/или распространения высокочастотного импульса. 1-ый способ использует рассеянный сигнал от одиночной группы импульсов в двухполосном частотном диапазоне для фильтрации в области «быстрого времени» (времени глубины) для построения сигнала с подавленным шумом реверберации, с чувствительностью 1-ой гармоники и улучшенной пространственной разрешимостью. В других способах излучают две или более двух групп импульсов в двухполосном частотном диапазоне, в которых частота, и/или фаза, и/или амплитуда низкочастотного импульса изменяется с каждой излученной группой импульсов. Путем фильтрации координаты номера импульса и корректировкиA new method for constructing acoustic images is introduced, which provides for obtaining images with reduced reverberation noise, obtaining images of nonlinear scattering and propagation parameters from an object, as well as methods for determining corrections for wavefront aberrations caused by spatial changes in acoustic propagation velocity. These methods have been used in various fields, such as acoustic images of geological structures, obtaining images of underwater objects using sonar, as well as in obtaining medical ultrasound images. The methods are based on processing received signals from radiated groups of acoustic pulses in a two-band frequency range with overlapping high-frequency and low-frequency pulses. A high frequency pulse is used to reconstruct an image, while a low frequency pulse is used to control the properties of high frequency scattering and / or propagation of a high frequency pulse. The 1st method uses a scattered signal from a single group of pulses in the two-band frequency range to filter in the “fast time” area (depth time) to build a signal with suppressed reverb noise, with 1st harmonic sensitivity and improved spatial decidability. In other methods, two or more two groups of pulses are emitted in a two-band frequency range in which the frequency and / or phase and / or amplitude of the low-frequency pulse varies with each radiated group of pulses. By filtering the pulse number coordinates and adjustments
