You are confused. The court cases didn't mention civilian, just military (Department of War and National Security).
I'm not confused, or at least I wasn't. I wasn't referring directly to any court cases. I was referring specifically to what you wrote where you brought up both civilian and military RADAR.
My reference to civilian was only this one time, and indirectly. So I'm ignoring the first wall of text as it doesn't apply.
It actually still applies since many of the details apply to any line of sight RADAR and the other details establish that, for basically any relevant land-based RADAR installation, the top of the wind turbines are over the horizon or very close to it. The "wall of text" that you apparently failed to read actually addresses details of both.
Are you an expert in military radar? No, no you are not. For one thing you wouldn't be going into detail about it publicly, and for another the below
There's nothing magical about military radar. The concepts are the same as other forms of imaging. It's either line of sight, or you're bouncing the signal off the sky, in which case you're going for a greatly extended range, which means that you completely pass over this wind farm so there's no interference. These wind turbines are tiny obstacles at that range. I pointed out in another post that the apparent height of these turbines, at the distance of 15 miles would be about the same as 1/3 inch at the distance of an outstretched arm. In other words, they would be appear about the height of a pinky nail. At the 35 miles to the mainland, they would appear about the same size as something 1/18 inch tall at the length of an outstretched arm. That's about the height of dime seen edge on. That's basically a speck. Even then, that's only if you can see its entire height over the horizon. At 35 miles, you would need a vantage point from an altitude over 800 feet to see the base of the wind turbine tower. The highest point in Cape cod is about 300 feet above sea level. If you exclude Cape Cod, the mainland is about 45 to 50 miles away and the nearest military RADAR installation in that direction even further. The simple fact is that there are very limited circumstances where land-based military RADAR could even "see" these because the horizon is in the way for line of sight, and they are not in the beam path for over the horizon either.
Also, are you really playing the game where you start out making technical claims about military RADAR, even though you are not a military RADAR expert and then, when I point out the flaws in your technical claims you turn around and say: "Are you an expert in military radar? No, no you are not."? I mean, really? Are _you_ a military RADAR expert? If not, your own reasoning should preclude you making your original claims.
All of our OTH systems were, in fact, far inland, because the minimal distance for their coverage was about 500 miles.
The "far onland" I was positing would be further than that. Basically I was referring to the inexplicable scenario where, for some reason, the over the horizon systems were placed so that their range stopped around where this wind farm is. I thought that was clearer it was meant to be an absurd scenario. Why did you think I wrote it?
Today we can do creeping waves, ground/surface waves, god knows what else, might as well call it detecting a "disturbance in the force" for all we know.
In other words, you have no idea what you're talking about WRT military RADAR and don't have any basis for a complaint against offshore wind turbines.
Your opinion is noted, what are you credentials for making it?
Well, thank you for noting my opinion oh great gatekeeper of knowledge who demands credentials but oddly provided none of their own. I am not a credentialed expert in RADAR specifically, but I have worked professionally with interferometric laser microscopy. Plus, you know, the basic knowledge of geometry and geography to know that these are almost, or totally out of line of sight of land based RADAR systems and that systems like OTH RADAR bypass them. Oh, also I know that the point of surface wave systems is that they rely on the conductivity of the water and aren't going to react with the moving blades that, at their lowest pass by over a 100 feet in the air. They will interact with the tower. Of course, they will also interact with boats. There's nothing special about a wind turbine to that sort of system relative to any other object of similar cross section.
The parts of a boat don't move at different speeds and a windmill blade does. It can hit 200mph+ at the tip and that's a real problem. I'm not a expert in military radar but I do know what a range gate is and what it is used for. Set it for 100mph and not a one of those boats will trip it so it won't show up on the return. But that turbine blade will.
I mean, I've covered all the other reasons it's irrelevant to the land based RADAR systems due to range, the horizon, etc. and covered the fact that, being an effectively stationary object at a known location, it could be compensated for. I even covered this already. If it were really necessary to try to see through the wind turbines taking up a tiny part of the field of view, and not just combine views from different angles, modern systems could use digital filtering and pattern recognition to determine the speed and orientation of the blades and filter out the results from them. You are making mountains out of molehills and you have simply dodged addressing the fact that, whether or not parts of boats are moving at high speed, they block the view much worse than wind turbines.
Speaking of boats you do know that most of those out that far will have radar. And that most of those are Doppler which is particularly affected by turbine blades. The Cape Wind project was examined and here's the quote: “The Coast Guard’s assessment of impact on navigation safety falls within the moderate impact level.” And that's only for the approach, I've not seen any studies what it like from within the windmill field. I would imagine it makes for a interesting radar view.
Oh, well, so much for this only being about military RADAR. There's basically no range from the wind turbines where this is ever going to be and more of a problem for boats than other boats would be. Aside from RADAR, they have charts. I went over all this already.
And now you can launch missiles and drones from behind it heading toward the radar and it will never see it coming. And how about the boats with their radar? How do they do that? You are not thinking this through.
I have thought this through, unlike you. I have mentioned over and over that a combination of methods will allow a complete view around the wind farm as well as how tiny an obstruction the wind farm is in the first place. You just obtusely ignore everything I've said and focus on each little thing as if it exists in a vacuum. Masking the areas with known obstacles does not exist in a vaccuum. We have already discussed comprehensive systems that can see past the wind turbines in the air, on the water, and under the water as well as see things inside the area of the wind farms, as well as past them. You are trying super, super hard to make them into a big problem, but they just are not one.
Go ahead, idiots have run me off the lake so I'm selling both of mine this year. I decided to ignore the rest because it's garbage. With the exception of ASW ships military SONAR is almost entirely passive. One of the things that is easy to detect and hard to hide are generators. Guess what is at the center of those turbine blades?
OK, sure, we'll just ban boats then. Got it. You don't like them any more, so no more boats for others.
Anyway, do you mean the generators in the nacelle at the center of the blades, 500 feet in the air? Well, it is called a generator, but I don't think it's the kind of generator you're talking about. More specifically, it's an alternator. The alternator itself is actually very quiet. You seem to be thinking of generators that are compound units containing a noisy internal combustion engine. As I have already pointed out, and you appear to be ignoring, the noise produced underwater by offshore wind turbines is actually very low volume compared to boats, and mostly in a very low frequency range usually only used for deep water, long range SONAR. It is not going to interfere with SONAR in any appreciable way.
Just the ones that protect our country from attack, nothing to see here, move along
You realize that we're talking about ones you could mount on the wind turbines to cover a small area that might be shadowed by the land-based RADAR, right. Pretty much what any of the boats passing by will have too?
I said that it seems like spite to cancel this. I said that I'm not a fan of canceling projects already approved. But as they argued in court that it's for National Security as recommended by the Department of War/Defense that there may be a valid reason for doing so.
Right, but then you argued like that wasn't just a pretext that, if it had ever been a real concern, would have been handled out of public sight for national security reasons? If something is already mostly built anyway, and it actually is a real security risk, it's just basic security _not_ to yell about it in public.
Everything else is a discussion of why that may be.
Right, but all the possibilities for why that may be turn out to be either total non-issues or, where there might be some tiny issue, easily handled. But then you're writing about how it will apparently allow concealed nuclear weapons to sneak in and EMP the country.
Doesn't mean I like it, or even agree with it. Now get off your high horse.
I generally only get up on my high horse when the other person is on theirs. Your initial response to TheMiddleRoad and then to me both seemed fairly high horsey. Honestly, while I may have come off a little sarcastic about boats being as big or bigger of an issue than wind turbines, if I look through my responses, I have not done much other than answer your questions and address your concerns and ask my own questions. I did perhaps over-react to your comments about nuclear power/breeder reactors, but that's because it was a bit triggering that it seemed so familiar from all the times I have had long discussions with people about renewables where they, over and over again, just ignored what I wrote to voice some exaggerated concern and then it finally comes out that they are just arguing against renewables because they are pro-nuclear and will accept no substitutes. Also, to re-iterate from earlier, it seems a bit odd to accuse me of being on a high horse, when you started demanding credentials despite presenting none of your own.
Anyway, to be clear on my position, I think that any actual concerns are overblown because, cases where the turbines are in the way are rare, the turbines do not block much at all, and there are numerous methods to work around that, only some of which I have detailed. The Trump administration's "concern" about interfering with military RADAR is exaggerated nonsense drummed up to retroactively excuse the action.
