NEXRAD project

I did a spy job for SRI (Stanford Research International) and they liked the result, so they put me in charge of the road crew that did the survey for the NEXRAD project.  That acronym stands for Next Generation of Radar.  You see it referred to on TV weather as Doppler Radar.  Same stuff.

We surveyed more than 100 prospective radar sites around the country.

We had two rigs, one was the travel trailer pulling a small trailer that contained our computer equipment.  The other was a heavy-duty pickup that pulled the trailer holding the tower.

The tower is pneumatic and could be raised to 125 feet.  With it, we could survey both the horizon and the radar environment.  The FCC had no data base showing who was transmitting on what frequency in any part of the country.   Every transmitter in that frequency range is required to have an FCC license.  Many didn’t and it was our job to discover the direction and frequency.  Some places were so cluttered with signals that there was no space in the spectrum for a powerful weather radar station.

This project was so political that it was very difficult to do the job correctly, imagine that:-)  We pulled up to one location in the Miami, Florida area and within a mile of our assigned testing spot, I could see several log periodic antennas trained on Cuba.  There was no way in the world that whatever agency was doing the snooping would tolerate our 50 kW of radar.  We would jam it up big time.  How come the person who did the pre-survey didn’t pick up on this?  It was because the person doing that job knew nothing about radio.  It wasn’t the only site that was totally wrong and a 5th grader could have known better.
