BeadwindowIt's not just AIS - that can be spoofed, turned off and simply not installed (under 300gT); there is a mix of RADAR in the Port areas, Dover TSS, combined with LRIT and VMS data; combined with visual reporting (dedicated and advisory air tasking) and intelligence (multi nation) reporting that is all fused.
Not matter what you try the smaller boats have a good chance for getting onto the channel undetected, especially if weather is on their side. The only alternative would be a huge string of EO/IR/AIS and RADAR chains along the coastline.
And then what, will that stop a yacht owner who has decided he's happy to take the risk and bring in a few people for pocket money?
For all those that speculated about these items, they're not there this morning. being the sad compulsive that I am I shall continue to monitor the situation. Fresh speculation on the ntaure of the now either dismantled or mobile items is welcome.
I don't know a great deal about radar, but surely the lilo would need a radar reflector or something? I am open to enlightenment to the contrary though........Interviewer says to bloke:
"So can all your detection kit identify these dinghies and other small boats they're coming across the channel in?"
"No, they're too small to be picked up"
The Channel is probably one of the busiest shipping lanes in the world: a contemporary snapshot of current trafficI don't know a great deal about radar, but surely the lilo would need a radar reflector or something? I am open to enlightenment to the contrary though........
That being said, the channel is not that wide and the MkI eyeball with a hefty pair of binos should ID anyone in a rubber ring coming across? Again, happy to be educated.....
I'm looking at the matter from an optimistic point of view, hence the minor change.@MrBane - your interviewee was (probably) being honest. Shore-based radar would have great difficulty in picking up something the size of a 2m inflatable (which seems to be the craft de jour) for such larks and japes.
Think about it: even with bodies on board, it probably doesn't present a profile higher than 1.5m or 2m wide. Now, put that in a sea running with a swell or a bit of a chop and a wave height of 2-3m and a background clutter of some BFO ships and Hey-presto!, our eager Doctors and Engineers are lost forever
I looked at the original, some were yachts on land so you could speculate many were AIS/Nav Beacons on vessels alongside, up canals, smaller channels or up onshore for sale/refurb etc.
