Radar Perimeter monitoring

This would be handy for the Groom Lake road and cheaper than Cammo
dudes.

Well, if it can tell the difference between a person and a bovine.....
I think the base has some RF based detection, but perahps not turned
on all the time. More than once I have had electronic items act oddly.
Case in point, a few of us were parked on the gravel by the ET
highway. Out of nowhere, the interior lights in my car turn on. Being
a late model vehicle, the lighting is computer controller, so
something triggered it. Another example is I had parked and locked my
car to go exploring in the range. Upon my return, I couldn't get the
remote to open the lock until I was nearly next to the car. I was
getting some sort of RFI.

Yeah good point.
It's hard to know how sophisticated the software is that runs it - but
watching a video on their site seems to the software tells the
difference in objects by how they move.

you guys are really kidding about all this aren't you , or
possibly making fun of the several uwbsarsurv-sats they moved off
from domestic assignments / testing ( to the mideast ) ?
those 1st gen uwb units have been airborne for several years, now
and even UAVs fly with 4th - 5th gen units attached to their
underbellies ! there are probably so many " birds " up now they are
practically bumping into each other. heard they were one of GW's
pet projects aimed towards border control as well ( probably built
by some of his business buddies h aha ha ha ) .
hear tell that "all " the important local " special " spots are still
being " toasted " 24/7 as they supposedly have for several years
now.
supposedly the navy owns the satnet ( I dunno , go figure ) hardware
but the cammo dudes are taped into some ( very little ) of it as
well. at least , the ones over this way are.
ground based surveillance radar went out with the covered wagon ......
heck you even see them ( the 15km 8087 jobbies ) on ebay from time
to time.

I'll point you to ( gesture at ) a little of the older associated /

notice , tho, this was a decade ago and it's miles and miles further
down that ole road nowadays ......... and then some .
those color -3d units were claimed deployed in the '04 - '05 era ,
some thought it was a bit earlier.
also heard rumors of it being mounted on the underside of awacs used
in red flag , maybe Miso has seen the pods ? dunno where those awacs
are parked at night.

The Nellis range is a place where it is hard to use airborne assets
It can be a wicked job of air traffic control. Just recall that Janet
they had to send to the TTR just to get it out of the way. Then would
you stage this snooper plane at the base? If so, fly it 24 and 7? I
don't think the place is that crazy about security given the buffer
zone is so wide.

I seem to recall some time in the 60s in
Popular Electronics. Hand held radar that
could differentiate between rain/humans/dogs
by the audio in the headphones.

Yes but no blue notes. Just blue hairs.

well you're right about that ............... ah hha ha ha
I think I used airborne incorrectly ........... just sub a-sync sat
in most of those airborne places . except the UAVs and the awacs .
sorry ........ ( hey if it's up there it's airborne to me )
and I'm only generally speaking of intrusion security .
sat intrusion security assets are a big deal in some circles and have
been in widespread use for years, over many installations ( down
here, up north and way up north for example ) . theres lots of
stuff around here " they " are ( rightfully ) uptight about , most
of it related to professional terrorist intrusions and materials
falling into the wrong hands, so they say. I'm sure theres other
reasons but no one is going to talk about those. actually , some
people appreciate the so called " lookie loos " as opportunities to
make tests and adjustments to equipment and as random tests of their
effectiveness , so I hear. in a few places , at least, " things "
are WAY past what most people might imagine when it comes to security.
uwb is where it's at .......... kewl stuff that uwb.
probably gonna see widespread uwb commercial / consumer apps in the
next decade .
just think of what the the military / government sat systems can do
. they monitor " everything " under the bird in 3-d color ( no not
the color of the object ) . all the way to sub surface. roofs ,
trees, concrete , sand , dirt , metal covers , aircraft .....
amazing stuff . they even see down into bodies of water now too
( no one is saying how well tho ) .
you've seen what XM sat radio can do with older technology , just wait
til ADT gets their consumer product UWB sarsurv sat birds up ayay
ah a ha haha ha.
think about this . if you could build a UWB sarsat beam footprint (
toasted ground ) detector ........ you might be able to drive around
different places and look for " protected " areas. this to discover
locations that the government is protecting .......... THOSE places
would be worth watching for sure. I suspect , tho, that most of
those " protected " areas would have large - wide buffer zones
protected by cammo dudes , same as it ever was. dunno if the foot
print would spill over outside the buffer zone or not . worth
thinking about .

snipped for brevity ( ha ) .........
>protected by cammo dudes , same as it ever was. dunno if the foot
>print would spill over outside the buffer zone or not . worth
>thinking about .
no , thats an old misnomer that seems to go on and on .........
I'm not saying there aren't plenty of surveillance sats that are
driven to locations and parked to do their job ( why do you think
Atlantis has to go up and refuel those turkeys all the time ? )
.......
but the nature of SARSats would make them a
much different animal. hypothetically speaking , of course ........
sarsat units need to be in motion to get their best image. by
moving they illuminate all those shadow areas and get multiple vector
bounces off the targets ( T-gnd , T-T etc ) , all this giving them
more 3-d information and eliminating " black " ( dead ) areas
and adding to 3-d resolution ( masking effect ) . think of it like
this as a simplified explanation ..... think of the GPS satellite
system and how those few birds are able to cover the entire planet ,
all the time , and keep at least 3 birds in view at all times.
now think of a similar network of sarsat birds but 3X ( maybe 10X+ )
more dense in birds , all tightly networked together and all under
control of multiple world wide ground stations ( if need be ) .
it would easily be possible to assign large amounts of ground
surveillance target sites to the network birds ( probably only
limited by bandwidth and available computer resources and these would
be state of the art huge ) there might be as many as ( say ) 9 or
maybe even 30 birds able to " see " any given assignment at any given
time , ALL moving , and adding to the resolution of the target
information ( or contributing to mass multiple target surveillance
situations in a different mode of operation )
like with cellfones but in reverse ......... as the sat or sats come
within view of a " target " area, they are switched from their
assignment of a few minutes ago and " view " their new assignment .
this because they are NOW in view of that / those targets. in other
words , this sat net can cover the entire planet 24/7 with a limited
amount of resources ( like GPS ) by smart switching and tight network
assignments and data collection / reflection. no doubt some amount of
processing would happen on the bird net ( pre conditioning /
collection ) but the vast majority of the imaging assembly and post
processing would happen on ground ( or sister processing sats also in
position and working sort of as collector / controller hubs on the
sat net ( eliminating some potential earth to ground issues and
making it easy for earth station assets to locate and access the nets
< solar flares emp etc. using bird resources shielded by the
earth's mass >) .
this has probably made things more confusing , but I hope it gives you
one scenario of how nearly any ( every ? ) place on the entire
planet " could " have multiple sarsat imaging taking place
24/7 ( from multiple angles from a net of birds with many different
perspectives and angles with simultaneous views ) and how this could
be accomplished with less resources than you ever thought possible !
( since " they " thought up the GPS sat net, it just takes a moment to
leap to this thought next . and GPS has been around quite a while eh
! ha ah ah a a )
I'm not asserting this is fact, this is only a hypothetical discussion
using obvious no-brainer extrapolations and drawing on current
well known technology as well.
