In this video I'll walk you through a complete example of how to build your own low cost two channel digital beamformer. At the end, we'll use it to track a 2.3 GHz RF signal and display its direction of arrival. The python files used in this video are found here: To build this yourself, you'll need: ADALM-PLUTO, rev C: Crystek CLPFL-2400 Filters: Antennas: Stand: SMA cables Other links used in this video: Pluto Dual Channel Modifications: Phased Array Beamforming: Understanding and Prototyping: Rapid Phased Array prototyping with Analog Devices and X-Microwave: Chapters: 0:00 Introduction 0:51 Agenda 1:56 Disclaimer! 2:58 Brief Overview of Beamforming Concept 4:11 Analog vs Digital Beamforming 6:21 Build our Beamformer 12:51 Calculate Expected Results 15:27 Program Beamformer in Python 19:46 FFT Plots of the Phase Shifted Signal 22:49 Array Factor Plots 26:48 Improve Setup 29:07 Direction of Arrival Compass 30:03 What's Next?
