Simulation of the Acoustic Field of Antenna Arrays

摘要

The article considers the reconstruction of images by Synthetic Aperture Focusing Technique (SAFT). The work compares additive and multiplicative methods for processing signals from antenna array. We have proven that the multiplicative method gives better resolution. The study includes the estimation of beam trajectories for antenna arrays using analytical and numerical methods. We have shown that the analytical estimation method allows decreasing the image reconstruction time in the case of linear antenna array implementation.
