Radar licence

A licence for radar? /forums/images/graemlins/shocked.gif

You are kidding?

Why would you not need a licence to radiate from Ofcom? S and X bands are not licence exempt, so obviously you'll need one.
 
I am sure we all know what radar stands for, but the question still stands. If you think about it there are many many applications all around us that transmit radio waves which noone holds a license for; so is this a definitive thing?
 
Yes, it's definitive, and I can't believe that anyone that's passed a vhf marine radio exam doesn't know that. Just look at any vhf radio licence application from Ofcom, and radar is listed.

Ship Radio Licensing: FAQs
1. What are ships’ radios used for?
Ships’ radio is used for the safe navigation of vessels and for making distress calls in emergency situations. It enables communication with coast stations, port/harbour authorities and with other vessels.

Ships’ radio can include MF (medium frequency), VHF (very high frequency), HF (high frequency), and UHF (ultra high frequency) radio equipment. It can also include satellite communications equipment, radar equipment, Emergency Position Indicating Radio Beacons (EPIRBs) and Search and Rescue Transponders (SARTs).

I can't believe we are discussing something so basic

Many applications transmit on frequencies that don't require licences. Radar transmits on frequencies that do. It is definitive.
 
It's entropy is non-zero, so it is a communication medium. (what would be the point if it did not communicate the presence of another vessel?)

And, as I said, it is on a frequency which requires a licence from Ofcom. Lots of items use the unlicensed ISM bands, but RADAR doesn't.
