Boreal Explorer (taiganaut@quitter.se)'s status on Wednesday, 11-Mar-2015 00:10:54 UTC Boreal Explorer #RANGER #millimeterwave #radar can 'see' you breathe in your home through the wall [VID] http://tmblr.co/ZhB8Yu1fWyhTd #surveillance #police @mcscx@quitter.se and Claes Wallin (韋嘉誠) repeated this. -
lnxw48 (Linux Walt) (lnxw48@fresh.federati.net)'s status on Thursday, 12-Mar-2015 05:46:44 UTC lnxw48 (Linux Walt) @clacke I wonder whether the signal is similar to the ones used in airport #crotch-scan machines. Claes Wallin (韋嘉誠) repeated this. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Thursday, 12-Mar-2015 06:16:51 UTC Claes Wallin (韋嘉誠) @lnxw48 Planning on wearing VHS-tape underwear next flight? -
Falk Duebbert (der@quitter.se)'s status on Thursday, 12-Mar-2015 15:24:28 UTC Falk Duebbert @clacke it's the way stealth coatings for ships work. Claes Wallin (韋嘉誠) repeated this. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Thursday, 12-Mar-2015 16:46:17 UTC Claes Wallin (韋嘉誠) @der Yes, that and deflection, which has the same drawback. So now you know that stealth technology is not perfect. ;-) -
Falk Duebbert (der@quitter.se)'s status on Thursday, 12-Mar-2015 17:00:16 UTC Falk Duebbert @clacke i wrote a thesis on DSP-based FIR-assisted RADAR, mainly on the clustered DSPs Claes Wallin (韋嘉誠) repeated this. -
Falk Duebbert (der@quitter.se)'s status on Thursday, 12-Mar-2015 17:03:01 UTC Falk Duebbert @clacke and there is active cloaking (something like Philadelphia Experiment - only just for radio and in reality and without Mr. Pare) Claes Wallin (韋嘉誠) repeated this. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 03:58:30 UTC Claes Wallin (韋嘉誠) @der Wow, I walked right into that one, didn't I? ZING! :-D -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 04:02:27 UTC Claes Wallin (韋嘉誠) @der So, did your approach include occlusion detection? If a coastline is discontiguous, and gap is moving, that should be good use of DSP. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 04:10:59 UTC Claes Wallin (韋嘉誠) @der Cool! Where can I read about this? A quick search gave me pseudo-science, non-informative pop-science and fiction. :-) -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 04:12:38 UTC Claes Wallin (韋嘉誠) @der Reproducing an echo that images what's behind me while retaining radar silence myself sounds really tricky. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 04:14:31 UTC Claes Wallin (韋嘉誠) @der Maybe detecting my opponent's echoes of things behind me and relaying them back would be possible. -
Falk Duebbert (der@quitter.se)'s status on Friday, 13-Mar-2015 06:31:13 UTC Falk Duebbert @clacke the system is for predicting a pedestrian's or biker's movement towards the street and the main sensorarray of a brake assistant Claes Wallin (韋嘉誠) repeated this. -
Falk Duebbert (der@quitter.se)'s status on Friday, 13-Mar-2015 06:35:08 UTC Falk Duebbert @clacke since medieval is over pedestrians don't wear metal that often so our RADAR was terahertz and FIR Claes Wallin (韋嘉誠) repeated this. -
Falk Duebbert (der@quitter.se)'s status on Friday, 13-Mar-2015 06:37:49 UTC Falk Duebbert @clacke no you just have to reduce the energy of your echo - radiowaves even of that frequency don't behave optical Claes Wallin (韋嘉誠) repeated this. -
Falk Duebbert (der@quitter.se)'s status on Friday, 13-Mar-2015 07:08:05 UTC Falk Duebbert @clacke you just detect your opponents main beam (an position), predict when the radar will hit you and cover yourself with noise. Claes Wallin (韋嘉誠) repeated this. -
Falk Duebbert (der@quitter.se)'s status on Friday, 13-Mar-2015 07:10:03 UTC Falk Duebbert @clacke opponents dsp will now try to distinguish between you and that noise. If u succeed, it will discard your echo. Claes Wallin (韋嘉誠) repeated this. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 16:32:22 UTC Claes Wallin (韋嘉誠) @der Ok, so they won't know where I am, but now they have noise. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 16:33:18 UTC Claes Wallin (韋嘉誠) @der Right, it's an arms race as usual -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 16:34:41 UTC Claes Wallin (韋嘉誠) @der Aha, cool. Very down-to-earth in application, but cool in implementation. :-) -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 16:35:57 UTC Claes Wallin (韋嘉誠) @der I figured if they can see a human figure it would be optical-like enough. But I'll take your word for it. :-) -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 16:37:35 UTC Claes Wallin (韋嘉誠) @der Cursed be that cotton and polyester stealth technology! -
Falk Duebbert (der@quitter.se)'s status on Friday, 13-Mar-2015 17:01:12 UTC Falk Duebbert @clacke as i understand it doesn't "see" you - it detects your movement, which is WAY more simple. Do you remember TRex in JurassicPark1? Claes Wallin (韋嘉誠) repeated this. -
Falk Duebbert (der@quitter.se)'s status on Friday, 13-Mar-2015 17:04:55 UTC Falk Duebbert @clacke and since it needs many sensors with great distance (compared to wavelength) it is more a triangulating System than a RADAR Claes Wallin (韋嘉誠) repeated this. -
Claes Wallin (韋嘉誠) (clackemovedtoheldscalla@quitter.se)'s status on Friday, 13-Mar-2015 23:55:11 UTC Claes Wallin (韋嘉誠) @der I admit to not having read the article, but based on what you are saying I see how just simple absorption would be very effective.
