a 6k$ drone costs 100k$ for a weapon lobby in an imperialistic country,so why they keep making war to sell weapons?!
because they enjoy war and blood,like movies and TV series...

For sure, russia is now and ever had been like that - already more than century rejoicing loudly over killing the scientists, engineers and artists, mothers and pregnants, children and just the farmer, then killing the these killers, then killing the Afgans, Chechs, Rumans, Baltians, Ukrainians, Georgians, Syrians, etc etc etc; and of course, own people as well; while actively exporting the Grandest ever the times idea: "You all live too much good, we may help (and oblige to help) You to live the same badly deep in ass as we live ourself".

What the crap does that mean?
It's the communist/dictator country that's making war.

 

All of this talk of trying new things when there is already a proven thing, that has been in use for years. It's called "iron dome". It could and should be used in Ukraine. https://en.wikipedia.org/wiki/Iron_Dome

 

Iron Dome = = Kipuc Barzeļ (Israelian language) or Kipat Barzeļ, probably Kippat Barzeļ (sorry, all my Ivrit knowledge is rather marketplace level language so sometimes I miss some nuanses). It is absolute excitement device worth to notify the flying object as well to prognoze its trajectory fast and accurate, but it method of destroy the target is rocket. Rocket for microscopic drone is like trying to kill anooyinf aedes with excavator cup. Too big and too clumsy. And sure, too expensive. But yes, I know Israelis was pronounced they made a gift of few Kipuc to UA, but WITHOUT of rocket bloke. Thus, the trevoga, trevoga, trevoga will sound but no rockets to shoot it down. At least so I read at Newsru.co.il just few days ago.

And yes, I never heard this Israelian Wunderwaffle be usead against the drones. It was made dedicatedly against Gaza sector rockets what they send every day 10 to 20 pieces onto Israelian homes.

 

Crutschow: squeeze Your hand. Well said!

Iron dome works but it's not a practical drone defense weapon.

A close-in defense with a wall of lead works too but it needs much better aim at the actual target path.

 

$100k missile successfully destroyed a $6k drone

The key in Ukraine is that a $100k missile saved untold millions in damage.

 

RE:""albeit one in which a $100k missile successfully destroyed a $6k drone""
That is the very hearth of the famous Israelian project Kipuc Barzeļ (steel coupole) what is very well computerized radar system automatically analyzing WHERE the Gaza sector outlaid bomb will fall. If fall in desrt, let it happen, but if fall over Israelian habitated cities, then on-the-fly that rocket is intercepted with probability of 96-98%. System is just excitment worth except the money - one Gaza rocket self-cost is 10 USD whilst one Kipuc Barzeļ shoot cost about 100 000 USD. Average year Gazaians are senting about 6000 such "gifts" to Israel.

That approach doesn't really work for drones since their destination can't be projected based on current track -- they maneuver. Furthermore, since they aren't ballistic, they can fly low and use terrain masking. The Ukrainians are actually doing a pretty good job against the drones, but some will always get through.

Agreed, but it's still a significant cost imbalance that has an effect on the relative ability of the two sides to sustain operations.

I wonder what old storage room those were in? In the middle 70's we still had a battery of HAWK's in the Keys left-over from the Cuba missile crisis.

They are getting very good on the Iranian "flying moped" birds.

 

Once again, consider simply overloading the RF sections of the GPS receivers. The frequencies are known, and overloading to the point of making reception of the satellite signal impossible will indeed take a bit of power. But jamming enough to prevent accurate navigation might be all that is needed. And with radar to see the path, the beam could be directed more effectively.

Or, nuclear carpet bombing.

OR a small submarine to finish taking out that bridge already damaged by a truck bomb. And then one drone to take out the madman running the fight.

 

Modern guided weapons, designed in a world of expected GPS denial, are hardened to simple RF overload jamming and are likely using internal IMU navigation/INS (Internal Navigation System) and localized sensors for terminal target identification and guidance. That said I don't expect the flying mopeds to have the most modern countermeasures but they will have some.

At the same time, an unpleasant surprise was found, a system was added to GPS guidance that prevents GPS signals from being changed by electronic warfare systems, but judging by the description, it does not prevent interference. The drone is also equipped with a primitive inertial system that allows it to maintain an approximate course and altitude if satellite navigation is prohibited.

That is, when the drone flies into an area where GPS signals are suppressed, the drone begins to be blown away by the wind, and it also runs into errors of the inertial system itself.

There is also the HOG-J (Home On GPS Jam) missile mode.

Even the hobby-level autopilots had inertial navigation capabilities -- jam the GPS and they simply fall back onto INS until they get GPS back. The drift can make it unlikely to hit a target needing a precise impact point, but if your just going after a city for terror purposes, that doesn't matter. The drones they are using aren't known for their precision strike capabilities to begin with.

Jamming from the ground is (or at least can) be a lot easier said than done, too. The airborne receivers are looking up with directional antennas and they often have very strong nulls pointing downward and to the side, specifically as an anti-jamming measure.

So,it was just not my word:

6k$>>100k$ means making weapon for making money is not a good bussiness anymore :E

 

RE""they can fly low and use terrain masking""
Particularly right but not for 100%. Because the visibility is primary dependent on reflection cross section. I wondered why I have obligation to install the radar reflector on my boat mast in 12 m high, what is some laughfully tiny catafot cylinder in 4 inck wide and 12 inch long if I have 12 meter long aluminium mast with width and breadth 8x15 inches. They say - because we cannot to see Your mast, but easily can see the reflector.... So, then I realized, mast pipe makes dispersing the light in all possible directions that resulting reflection toward radar are coming, probably, from 1/10 of mm2..... So, deduct that round formfactor is that thing making no reflections, and drone may be rich of such quality. Plus the reflections from Ground and indeed, it isnt easy to see drone except if one specially seeks for drones.

"REtro REfleactors" are a special case of reflector that uses prisms to reflect an incident beam back towards the source. There was one put in place by the US moon visit a few years back, and it was able to return a laser signal to earth. And those reflective highway signs use some form of retro-reflector as well.

 

"REtro REfleactors" are a special case of ......

I said it already. Those prism corect technical name is Cataphot. And why I said, its fixing the fact that 2 dm2 of plane retro-reflection is much better visible in radar than about 2 m2 but curvy surface.

 

On further reflection, it might be possible to solve the problem at the source. Offer to lift some sanctions on Iran if they stop selling munitions to Russia. And if natural gas from Iran could reduce shortages in Europe and reduce the need for Russian gas, that's a bonus.
