I'm aware that if this were possible someone smarter than me would've figured this out long ago, but could someone tell me the problem with this and why it hasn't been done?
Why can't airborne ground penetrating radars be used to spot mines?

Pick one. Ground-penetrating radar has to be in contact with the ground to work.
Not always, near GPR allows for lower frequencies useful to go many meters deep, something not needed to detect mines.

near field GPR

They can. But before modern signal processing it was impractical, so it's only getting implemented in the last ~5 years. If you go to an arms trade show in Dubai you can buy octocopters with GPR from an American minesweeping wand, with a power tether to your car driving behind while it hovers over the road. Still somewhat impractical tbh.

It's being done. Read this.
The precision demining mortar has a 20 shot magazine. At 6 per breach that's a lot of dead AT mines.
Kino. I wonder how you could pair this with using thermals after sunset to find the temperature difference as a spotting method. I also wonder how practical directed energy is for detonating mines. Could microwaves be used?
Idk about HPMs (although blanketing a zone with HPM shots will probably be the new suppress by fire) but demining lasers like Zeus III were used in Iraq with modest success and demining modes are advertised for some modern ones.
It does work, in fact you can even do mine recon using thermal vision.
The issue is that if your enemy sees you doing this, it will give them warning about an immanent attack.
It's also usually the case that holes in minefields are deliberately designed to funnel forces into unfavourable positions and remote mining systems can effectively close these kinds of corridors on short notice.
It would be great for use in the post-war era, or in areas that have already been conquered by advancing troops but remain mined, but it's not well suited to the front lines.
The minefields that are blocking the advance of Ukrainian troops are not left unattended. They sit in front of Russian defensive positions, and if the Russian soldiers see a helicopter slowly making passes back and forth across the minefield while it scans for mines, they're going to go get a MANPAD and shoot it down.

Modern radar tech is sadly unappreciated on /k/. We have posters who think filtering birds or finding drones are still problematic lol.
/k/‘s iq and literacy has dropped drastically in the last twelve months. Lots of new retards who think drones are the end of history because the only thing they know about war is Russo Ukraine killcam footage, both redditors and thirdies who are excited to think maybe they can destroy America
Buddy, we're about 5 years away from cell phone towers being capable of doing that 3D room-penetrating scanning from the Dark Knight. Google Joint Sensing and Communication. You won't even need dedicated radar soon, just passively listen for reflections from 5G/6G cell phone towers. Similarly, for mine-sweeping just pass what is basically a big WiFi hotspot over it and look for pings.
We do this already using this radiation. We just need a passive directional receiver near your house and we can sense your movements inside it. This is current technology being currently used by several armies
Two antennas on a wifi router is enough. Can be done with remotely hacked firmware.
No it’s not. You need three receiving antennas for directionality. This is basic physics. A Wi-Fi router has only one receiver
Give this a read and bear in mind it’s a bit dated
Transparent battlefield indeed.
>X-band
Doubt it'll be able to do anything NOSS satellites couldn't do in the 70's. Penetrating ability of X-band is so-so. You need lower frequencies to better penetrate through solid obstacles.
You're looking for synthetic aperture radar. Footprints, mines, whether you've mowed your grass this week. They can see it.
If I'm not mistaken, the problem is the lack of useful accuracy. They can tell the soldiers that yes, the area is mined. But do t have the precision to be able to plot out a course for the soldier to walk through.
Couldn't you defeat it by sprinkling chaff on the ground?
It would have to be more of a "decoy mine," designed to simulate several key features to resemble a real mine. If radar were being used, it is almost certainly being used in conjunction with other methods (thermal imaging, for one example). Why would you even build a radar drone if it didn't also have thermal and other imaging capability to overlay on the radar image? This is the kind of shit you want to be Just Very Certain About, so you use as many investigative technologies as possible and cross-reference all the data/images.
So, theoretically, your point could be possible ... but, then, you might as well also lay down real mines since they are about as cheap as a good decoy could possibly be. Might be some specific instances where a decoy could be quite useful, but I expect almost always that if you can put down decoys, you might as well use the real thing.
So what's the use case? It can't be used on the active frontline, and in the peacetime humies have to check everything manually anyway and they have no time constrictions.
