TLDW: A 1970s over-the-horizon radar for ICBMs that apparently didn’t work very well. https://en.m.wikipedia.org/wiki/Duga_radar https://en.m.wikipedia.org/wik

  I couldn't quite figure out from the video if it was an early launch detection system and/or a signal jammer. Cause the video mentions both. A cursory glance at the Wikipedia article also didn't clear it up. Does anyone know?

    From reading the wikipedia article it seems like it was primarily a launch detection system that had a side effect of jamming signal.

    It was a detection system, but it operated on frequencies that already in use by shortwave broadcast stations (much more prevalent then than now), amateur radio operators, etc and interfered with them. You can get more details on how it and similar systems work at https://en.m.wikipedia.org/wiki/Over-the-horizon_radar https://en.m.wikipedia.org/wiki/Over-the-horizon_radar

  Fun fact: The radar in PUBG was based off the Duga radar.
