Or do you mean using phase information from the receive antennas to reconstruct the environment rather than using phasing at the transmit side to steer your beam? That's a very interesting idea since it can give you a 360 degree view with no need to steer your beam, in the same way that some blind humans can use clicks to get a picture of their entire environment. (I use humans and not bats because I think bat sonar is pretty directional, whereas human ears can localize sound quite precisely without any need to turn one's head.) > > > > > > > > > > > > > > > > > Beam stearing be accomplished much cheaper than via a phased array using nearfield plasmas to block or steer the beam. For example, a vertical cluster of flourescent tubes surrounding a simple dipole can, with proper circuitry, quickly switched so that only one of the tubes is "off" (transparent) at a time allowing incoming/outgoing signasl to only propagate in that direction. The other tubes are "on" and reflect the signals. > > > > > > > > > > > Sure, if you don't care about MIMO, there are lots of ways to steer your beam using relatively cheap circuitry. You can have multiple transmit/receive antennas and just adjust their relative phase. AIUI this is how the LoJack locators operate. Switching reflectors on and off independently as you suggest here would allow multiple beams, though their relative phase would not be adjustable. It all goes toward the goal of minimizing the amount of energy you emit that isn't directed toward the receiver, though. > > For privacy in ptp links and a highly directional antenna (e.g., a parabolic dish) one can take a cue from covert radar tech. Alice geometrically moves around the transmit signal, and thus far-field phase, using a "matrixed" near-field feed that switches randomly at >> than the symbol rate. If you can adequately suppress the switching noise the phase shifts make it near impossible for an off-axis (> 0.5 degrees for a 32-element 2D feed) Eve to even detect that a signal exists. Bob, all other things being equal, using a standard receiver, should have no problem with receiving. This tech is practiced only at the antenna and, like Orbital Angular Momentum, should work with near any emission type or protocol without need modify other equipment. > > Thanks for posting the latest version of your slides.

I wouldn't think law enforcement DF equipment would be fooled by such a thing, since for example FCC will often be looking for people who are outputting too much power, which on the ham bands is going to be multiple kilowatts (I think they've mostly given up on CB except when it starts interfering with licensed users). > > > > > > It MAY be possible to use SDR to achieve LPI while still remaining within > > > > if you're building LPI, you don't give a fuck about the FCC (compliance). > > by definition, if they've found you, you fucked up! > > > > +1 > > > > > Perhaps, but I'm not about to suggest that anyone break the law. > > > > > > Actually, that gives me an idea: MIMO precoding[2] (versus spatial > > > multiplexing, which is useless for your purposes).

The talks are aimed at allowing British authorities access to a range of data, from interceptions of live communications to archived emails involving British suspects, according to the officials, who are not authorized to comment publicly. ... Under the proposed plan, British authorities would not have access to records of U.S. citizens if they emerged in the British investigations. Congressional approval would be required of any deal negotiated by the two countries.

Zenaan, I think we must say (also) the following before starting this thread: > ""Before going any further, let me also immediately say that I am not > talking about Jews or Anglos as a group, but I am referring to the top 1% > within each of these groups. Furthermore, I don’t believe that the top 1% > of Jews cares any more about Israel or the 99% of Jews than the top 1% of > Anglos care about the USA or the Anglo people"". > The "plain" anglos/jews should not be insulted by this term (Anglo-Zionist). It's not about the nations, but about a rotten ideology of the ruling elites of these nations/coming from these nations (and about those blind/scum people supporting them). It is crucial to remember because i see many people get insulted by this term (yes, we are emotional beings) instead of focusing on what it is about. > Zenaan Harkness Sun, 07 Feb 2016 14:54:12 -0800 > > OK, I'm going to take the /dev/zero redirections. > > This article is rational, as far as I can tell, but hey, my powers of > ascertaining rationality m > > ay well not match yours. > > I say this is on-topic regarding the political correctness gone mad > discussions.

OK, I'm going to take the /dev/zero redirections. This article is rational, as far as I can tell, but hey, my powers of ascertaining rationality may well not match yours. I say this is on-topic regarding the political correctness gone mad discussions. On topic as in, bang on topic.

In iceland, some portion of mortgage debts were forgiven also: "Reports from 2012 (many of which were written by U.S. media outlets) noted that while Iceland forgave a large amount of mortgage debt in order to boost the economy's recovery from a financial crisis, this action did not entail entirely wiping out all home mortgages held by all citizens of Iceland. Rather, it involved forgiving a portion of some mortgage debt that was tied to inflation:" http://www.snopes.com/iceland-debt-forgiveness/ Sad thing is, a great story got bullshitted by sensationalist crap news, and so Snopes has a field day saying how false it all is, although they do provide the above quoted paragraph to their credit.
