You guys know if they come in at a hundred feet, you can't see them with a regular radar because you
don't have line of sight over the horizon because of the curvature of the earth. So what they did, two
guys from Ukraine, doctors that came and briefed me at Ramstein did this in their garage with their own
money and they made this happen. What did they do? They grabbed 8,000 cell phones, and they put
them on a six-foot pole and they put them all around the Ukraine and they put a microphone like this
next to it so they could hear the one way UAVs coming overhead. Cost $500. They were able to get
headings, they're able to get velocity of these things. And then they put that into a computer system
that went out to 200 mobile training units that had AAA and they had trained a guy for six hours to sit in
the AAA and look at an iPad that would show them where the UAVs were coming in.

They had 84 of them that came in the other day. They tracked all 84, they shot down 80 with AAA. That's
on the right side of the cost curve. As opposed to shooting them down with Patriots and SM-2 missiles.
Just think of what just happened. One way UAVs put everyone in the game, to include the Houthis. And
when they did their attack on 18 October, they had 21 come over at $7,000 a piece and we shot them
down with $700,000 SM-2 missiles. That is not the right side of the cost curve. We need to be thinking
this way as well. Can we get some low cost things to take down this, what we know is going to be one
way, UAVs coming our way? AAA, directed energy, things with a deep magazine, microwave, there's a
bunch of things out there, but we need to think about that to protect ourselves against that threat that's
going to come in swarms.

What the Houthis did, what Russia's doing is nothing compared to what we're going to see in your
theater later on and at very small cost they can do this. We need to do this ourselves. We talked about
the value of partners. I have a lot, 31 great partners in NATO, soon to be 32. Not all of them can afford F-
35s, but they can all afford a $10,000 UAV. If we start doing the same thing, we'll get 15 other partners
involved. They can launch and put a bunch of these if we have to, across Indo-Russian, and now we can
empty their magazines where they're taking SA-22s, SA-21s and 23s going after $10,000 One-Way UAVs
that a partner produced and it cost us no money because they wanted to be part of the war. And now
we just found a way for them to be part of the war and really part of deterrence. So that's a big lessons
learned that we've had in our theater.

Ehk siis, Ukrainas tegid paar tüüpi seirevõrgu. Audio põhise, ilmselt korralike mikrofonidega + mobiiltelefon sideseadmeks.
Ja seirevõrk suutis avastada madalal lendavaid mopeedi tüüpi droone, ja enamus neist korjati ära õhutõrje kuulipildujate ja kahuritega - odavalt. ....

Kunagi käis ka siit foorumist läbi mõte, et "madalalt liikuva tehnika avastamiseks" kasutada autonoomseid mikrofone aga see laideti mõistmatuse tõttu maha.
Seliseid "mikrofone" saab paigaldada suvalise elektriliinimasti (toite saab samast liinist) otsa ja need saaks anda infot ka teeliikluse kohta. (Töötavat tankimootorit on kuulda kilomeetri kauguselt.)
Liinidest kaugemal saab kasutada akut ja päiksepaneeli "mikrofoni" toiteks.
