For beamforming or phased array antenna design with massive antenna ports, this program enables simultaneous phase and amplitude input across all ports, featuring automated optimization routines and parameter adjustment algorithms.
Beamforming, also known as spatial filtering, is a signal processing technique used with sensor arrays for directional signal transmission or reception. This technique involves combining phased array elements in a way that signals at specific angles experience constructive interference while experiencing destructive interference at other angles. Beamforming can be used at both transmit and receive ends to achieve spatial selectivity. Compared to omnidirectional patterns, the enhancement in reception/transmission is referred to as receive/transmit gain (or loss). Beamforming can be implemented with radio waves or acoustic waves, finding applications in radar, sonar, seismology, wireless communications, radio astronomy, acoustics, and biomedical fields. Adaptive beamforming represents
MATLAB code for phased array design and synthesis using Fourier transform techniques with comprehensive algorithm explanation and implementation details
A simplified model of phased array ultrasonic flaw detection and imaging system capable of simulating imaging results for three different acoustic beam types, suitable for understanding ultrasonic flaw detection principles with configurable beam parameters and material defect visualization.
Utilizing the Field II simulation software, this implementation models dynamically focused ultrasound phased array imaging. The simulation is contained within a single main function that can be directly executed within the Field II environment, requiring no additional setup or dependencies. This approach efficiently captures the core beamforming and focusing algorithms used in ultrasound imaging systems.
