3D Radar

When I was a radar instructor at RMCS, the target was "seen" once per aerial rotation. Now a supersonic tennis ball can be tracked from 25 km away, and drones followed too. See this for interest.

That's interesting Dobra

My late husband had connections with Radar too and was seconded from RMCS to the RSRE.
I don't want to give to much away on a public site .

Re: 3D Radar

I thought they nowadays had things called " phased arrays " where the antenna doesn't physically move but the transmitted and received wave fronts move because of variations in the timings between the individual radar transmitter receiver units?

I read your link Dobra and I suppose it is all down to the sophisticated high speed computer processing used and the even more sophisticated mathematics underlying it.

In medical MRI scanning for example the actual detectors are just one or perhaps 4 simple coils and a single voltage on each. But that combined with the data on the magnetic pulses being transmitted during the scan enables a huge amount of data to be extracted. Very probably the name of that chappie Fourier and his transform is involved or at least I know it is in medical imaging.

If that seems difficult to comprehend then just think that the signal coming down to your digital TV is a single instantaneous varying voltage but the clever processing over time can yield a huge amount of data!

Hi

A Bond Girl no less.

I shall now refer to you as Ms Moneypenny

I do hope that you bought shares in them when they were privatised.

Re: 3D Radar

More like Ms Penniless Gibbs
Shares in the 'Q' place, I wish.

Re: 3D Radar

Hi

Thank you for that Dobra.

Stealth Planes, well the technology is 30 years old and now easily tracked.

It does make you wonder what the military have up their sleeves now though.
