fv1609 Posted July 28, 2013 Author Share Posted July 28, 2013 A means of covertly transmitting orders to troops in the jungle? Andy So very very close Andy. So how would the system operate? Quote Link to comment Share on other sites More sharing options...
Lauren Child Posted July 28, 2013 Share Posted July 28, 2013 oooo. How about hot-air signals like smoke signals, or maybe bouncing the IR light from the cloud layer? Or maybe microwave into the water droplets in the air (a poor mans troposcatter?) Quote Link to comment Share on other sites More sharing options...
Locolines Posted July 28, 2013 Share Posted July 28, 2013 Would this operate in conjunction with another 2 of these Like triangulation ? Quote Link to comment Share on other sites More sharing options...

All ingenious stuff Lauren but not that complicated (ah troposcatter & rain scatter used to do a lot of that on 10GHz used to get further than on 2 metres ) Quote Link to comment Share on other sites More sharing options...

Lauren Child Posted July 28, 2013 Share Posted July 28, 2013 Balloon/aerostat with signal lamp?- I'm guessing it must have to be high up to get direct line of sight to the IR receiver. Quote Link to comment Share on other sites More sharing options...

gazzaw Posted July 28, 2013 Share Posted July 28, 2013 IR Heliograph that can only be picked up by a similar receiver or relay/rebro device? Quote Link to comment Share on other sites More sharing options...
Locolines Posted July 28, 2013 Share Posted July 28, 2013 Ok , so the beam or signal is pointed at the destination for troops and if the signal of sound gets broken or interrupted then they adjust their direction until they get a good signal again.... A bit like what bomber command used over Europe ? Quote Link to comment Share on other sites More sharing options...
fv1609 Posted July 28, 2013 Author Share Posted July 28, 2013 IR Heliograph that can only be picked up by a similar receiver or relay/rebro device? Yes Gary sort of, but more sophisticated than that but in a different direction Quote Link to comment Share on other sites More sharing options...

Lauren Child Posted July 28, 2013 Share Posted July 28, 2013 Lauren where were you thinking they would have a receiver? Ah, good point - I'd assumed this was the receiver and there would be heat/IR from another source to pick up. If this is a sender, could the receiver be as simple as a chap with IR goggles?

andym Posted July 28, 2013 Share Posted July 28, 2013 So very very close Andy. So how would the system operate? There's obviously something overhead that the thingy receives infra-red messages from. A helicopter with matching transmitter? Andy Quote Link to comment Share on other sites More sharing options...
Lauren Child Posted July 28, 2013 Share Posted July 28, 2013 Don't understand Lauren. But did you see my second reply to your post on the previous page? I was wondering if line of sight was achieved using underground pipe/tunnel. You mentioned "buried" and asked for more information when I mentioned mine marking, so I thought that had the makings of a Crafty Clive Clue Quote Link to comment Share on other sites More sharing options...

If this is a sender, could the receiver be as simple as a chap with IR goggles? "I'd assumed this was the receiver" In that case you have one well done Lauren! When I re-read it I wasn't sure which way round you had it. Up until now everyone seemed to assume this was an IR source of some sort Quote Link to comment Share on other sites More sharing options...
