Digital Beamforming of Echo Signals from 16 Array Sources

Digital beamforming of echo signals from 16 array sources involves echo signal simulation, Taylor window weighting optimization, digital mixing operations, and beamforming processing simulation. Specifically, digital beamforming is a signal processing technique that enables directional reception and enhancement of multiple signal sources through echo signal simulation and processing. The implementation typically involves: first simulating echo signals using array response modeling; then applying Taylor windowing to the beamforming weights to reduce sidelobes (commonly implemented using MATLAB's taylorwin function with specified sidelobe level parameters); followed by digital mixing operations for frequency translation (often achieved through complex multiplication with local oscillator signals); and finally performing beamforming processing using phase shifting and summation algorithms. Through these steps, effective digital beamforming of 16-array-source echo signals can be achieved, enabling signal enhancement and directional reception. The complete workflow can be implemented in MATLAB using phased array system toolbox functions for array geometry definition, signal generation, and beamformer objects configuration.
