Wouldn't an 850GHz signal be lost if an insect flew between sender and receiver? Isn't that going to make it pretty impractical? Honest questions. I could easily be missing something.

High-res radar seems viable, though.

The term "line-of-sight" typically refers to the obstacle presented by the curvature of the Earth or large metallic objects[1]. An insect would not block a THz EM wave, just as the walls of your home (probably) don't block your cell phone's radio.
