For reasons we don’t need to delve into here, I’ve recently been writing about phased array systems in the context of cellular communications and super-spiffy radar systems.

The reason I mention this here is that it can be tricky to explain the phased array concept to beginners. However, my chum Matt Pulzer, who is the editor and publisher of Practical Electronics magazine in the UK, just shared this video with me.

All I can say is that this is one of the best explanations of how phased arrays work I’ve seen this far. Plus, now I want to build my own super-duper DIY sonar scanner. How about you? Do you have any thought you’d care to share about phased arrays in general and this video in particular?
