摘要

平移孔径算法(TAA)是一种新的角散射成像方法。本文利用k空间理论对TAA进行了分析，并利用仿真工具PSF进行了仿真。通过分析两种采集孔径几何形状的相关系数，计算了TAA的有效景深。提出了一种校正方法来校正不同系统几何形状的相位差，并分析了各种常用的孔径结构对TAA的影响。

Analysis of C- and D-weighted imaging using the translating apertures algorithm

The Translating Apertures Algorithm (TAA) is a novel method for imaging angular scatter. This paper presents analysis of the TAA using k-space theory, and simulations performed using a simulation tool, PSF. The effective depth of field of the TAA is calculated by analyzing the correlation coefficients between the two acquisition aperture geometries. A correction method is proposed to correct for phase differences in the different system geometries involved, and various commonly used aperture configurations are analyzed for their effect on the TAA.
