New radar, anyone?

Shame santa isn't real - I want one!


200ft to 32nm at 20w, instant on, stand by 2.9w.

200ft to 32nm at 20w,

Just noticed -
At the same time!

Impressive, or what!
One thing, though. If the dead zone around the boat is eliminated, how would 4G work on a saily boat where there is no 360 uninterrupted view?
Would there be no blind spots created by masts or forestay?
Pulse radar can live with sticky-up bits, the dead zone being the downside.
Thoughts?

Hadn't occured to me before but if Broadband 4G can pick-up a PVC post at 500/600 ft it mights have a significant role to play in MOB situations in choppy seas.

It is pity my Raymarine equipment isn't compatible. At the Southampton Boat Show, Raymarine were very dismissive about broadband radar technology and gave me to understand they don't intend to produce one themselves.

Presumably only if the MOB is equipped with some kind of pole. I can't imagine a radar picking out a head between waves.

I think that there would be quite a bit more above the water than just the head & wonder whether the head+the shoulders+the upper chest/neck+the top of an inflated life jacket would be be sufficient to show - particularly for a scanner mounted at high level on a mast? My guess would be that the surface area above the water would at least equivalent to the PVC pipe shown in the Simrad video? Perhaps reflective patches be added to a life jacket or doesn't broadband radar work like that??

It may be that a good radar could pick out such a target in smooth water - but in that case you could see him with your own eyes. If it's rough enough that the waves obstruct your view, I would expect them to disrupt the radar too. It's not a matter of the cross-section per se, but what's around it. A post sticking up clearly into free air is different to a lump surrounded by other lumps, one made of flesh and the others made of water.

What's the pricetag for that then? I'm after a radar.....

Curious to know how they get 36nm range?
That's got to be well below the horizon even for a scanner on a yacht mast looking at the bridge of a tanker.

Al you need is a little bit of ducting to get that.
