Finally, in the topic of navigation interference, we got to the coolest and most interesting. Moreover, this interesting turned out to be not so difficult technically.

This is interesting - spatial processing of signals from antenna arrays. In ordinary, especially amateur, radio communication and radio navigation practice, this is still rare. This is due to the additional multiple costs for the number of radio paths. But sometimes this is perfectly acceptable. For example, in mobile communications. Spatial processing, MIMO, is widely used here. Even a regular WiFi hotspot has had it for a long time.
