In this chapter we cover the concepts of beamforming, direction-of-arrival (DOA), and phased arrays in general. We compare the different types and geometries of arrays, and how element spacing plays a vital role. Techniques such as MVDR/Capon and MUSIC are introduced and demonstrated using Python simulation examples.

Beam-forming functions from "Lightweight and effective sector beam pattern synthesis with uniform linear antenna arrays". Examples found in their language folder.

Jul 8, 2021 · This python package aims to implement signal processing algorithms applicable in antenna arrays. The implementation mainly focuses on the beamforming and direction finding algorithms. For array synthesis and radiation pattern optimization please check the "arraytool" python package.

For linear arrays, theta is a 1D array of angles (in radians) with 0 being broadside. For planar and 3D arrays, theta is a 2D array with an (azimuth, elevation) pair in each row. Such arrays can be easily generated using the arlpy.utils.linspace2d() function.

An antenna array can be used to direct radio waves in a particular direction by adjusting their number, geometrical arrangement, and relative amplitudes and phases (see e.g. S. J. Orfanidis, Electromagnetic Waves and Antennas, Rutgers University, 2016.)

Basic delay-and-sum beamforming routines in Python for demonstration purposes. https://github.com/fchirono/BeamformingBasics. This Python package provides some basic functions for creating...

We may now visualize the array’s radiation pattern by specifiying the beamformer’s transmitting focus point and calling the plot_pattern method. Let’s extend our simulation to evaluate our custom base station’s performance in a urban communication scenario.

Mar 23, 2017 · The Array Factor demonstrates that by altering an element, such as its position or phase, we can alter the arrays properties. For example the arrays beam could be steered to a desired...
