Abstract:

Статья посвящена разработке эффективных методов 3D акустической томографии. Обратная задача рассматривается как коэффициентная обратная задача для уравнения гиперболического типа относительно неизвестных функций скорости звука и коэффициента поглощения в трехмерном пространстве. Математическая модель описывает такие явления, как дифракция, рефракция, переотражение и поглощение ультразвука. Трудности решения обратной задачи связаны с ее нелинейностью. Предложен метод низкочастотной 3D акустической томографии, который основан на использовании коротких зондирующих импульсов двух центральных частот~$f_1$ и $f_2>f_1$, не превосходящих 500 кГц. В качестве алгоритма решения обратной задачи используется итерационный градиентный метод на частоте $f_2$, в котором в качестве начального приближения используются распределения скорости звука и коэффициента поглощения, полученные как результат решения обратной задачи на частоте $f_1$. Эффективность предложенного метода акустической томографии проиллюстрирована решением модельных задач при параметрах, близких к задачам ультразвукового зондирования мягких тканей в медицине. Предложенный метод низкочастотной 3D акустической томографии позволяет получить пространственное разрешение порядка 2--3 мм при контрасте скорости не более 10%. Разработанные алгоритмы легко распараллеливаются на GPU-кластерах. This paper is devoted to the development of efficient methods for 3D acoustic tomography. The inverse problem of acoustic tomography is formulated as a coefficient inverse problem for a hyperbolic equation where the sound speed and the absorption factor are unknown in three-dimensional space. The mathematical model describes the effects of diffraction, refraction, multiple scattering, and the ultrasound absorption. Substantial difficulties in solving this inverse problem are due to its nonlinear nature. A method of low-frequency 3D acoustic tomography based on using short sounding pulses of two different central frequencies not exceeding 500 kHz is proposed. The method employs an iterative gradient-based minimization algorithm at the higher frequency with the initial approximation of unknown coefficients obtained by solving the inverse problem at the lower frequency. The efficiency of the proposed method is illustrated by solving a model problem with acoustic parameters close to those of soft tissues. The proposed method makes it possible to obtain a spatial resolution of 2--3 mm while the sound speed contrast does not exceed 10%. The developed algorithms can be efficiently parallelized using GPU clusters.

Abstract:

The paper presents the results of computer simulation of the developed dual‑frequency antennas with a common radiating aperture, operating in the millimeter and centimeter wavelength range. The operation of antennas in the Kaand W‑bands is based on the well‑known dual reflector polarization rotating antennas constructing principles. The twistreflector of the considered antennas is combined with the radiation surface of the centimeter wavelength range (X‑band) waveguide‑slot array. Transreflector is made by offset scheme. For the Kaand X‑bandsantenna, the transreflector is a paraboloid of rotation part. In the case of the Wand X‑band antenna, the transreflector has a flat Fresnel zoned antenna structure. Computer simulation is based on the method of finite integrals, which provides a reliable result at an appropriately chosen sampling step. The calculated characteristics confirm the operability of the considered antenna options.

Abstract:

In this work an overview of numerous possible processing modes in future dual frequency, dual constellation GBAS is given and compared to the current GAST D standard. We discuss the individual error contributions to GBAS protection levels and give an overview of the general processing. Based on this the consequences when adding a second constellation as well as frequency are investigated. Geometrical implications and changes to the residual differential error bounds are studied separately first. In terms of geometry a comparison between the single and dual constellation case is presented using dilution of precision as metric. The influence on the different sigma contributions when using new satellites (Galileo) and signals (E1, L5, and E5a) is individually discussed based on recent measurements. Final simulations for different varying parameters are carried out to compare relevant processing modes in terms of achieved nominal protection levels. A concluding discussion compares the outcomes and analyzes the implications of choosing one or the other mode.
