Default radar and health ?


Anyone that was involved with the Nike Hercules missile system in the
late Fifties and through the early Seventies was around high powered
pulse radar. It was deployed around major metropolitan areas in the
States and other places around the globe.

All the tracking stuff was short pulse "X" band and maybe a couple
hundred watts average.

But the big stuff was the acquistion or search radar that was "L" band.
The one I worked with in Korea was maybe 5 or 6 megawatts peak and 4 or
5 kw average on the "L" band.

Some Stateside sites had the big G.E. "L" band job that was fairly long
pulse and put out 10 megawatts peak and 18-20 kw average. I was real
pleased that it had a rack mounted Bird wattmeter and I was impressed
to see a solid 18-20 kw average power running through the waveguide to
the antenna.

The range radar was Ku band (15-17 kmc) (TRR to you Nike guys) and one
of the old timers I worked with told me that if you directed the
antenna towards an individual, he would feel the heat. And I'm sure
that's true. We're all familiar with microwave cooking.
