True. About two to three weeks before the TWA-800 disaster, a fully loaded and ready tripod mounted missile was discovered by a county sheriff's unit set up on a dirt road about four miles from the airport that TWA-800 took off from. It was armed and ready to go. It had a missile in the launcher, ready to go. . . Just no one there to launch it.
They explain it away. . . by giving no explanation of where it came from or why it was there. I guess it was just road-side litter. Such a launcher missile combination was easily worth over a million dollars on the underground market at the time, but it was abandoned on the road-side for some unknown reason.
As for using a radar to ping the plane, such a guidance would have lit up every receiving radar antenna in the area while it was doing it. . . and the number of return pings from TWA-800 would have been a dead giveaway that something was up. Instead we have only the official return pings from the transponder ever 4.64 seconds.

I have not heard of this. Perhaps this was an earlier attempt which was discovered and aborted?

I do not know if any shore equipment would have recorded excessive pings, or even if it did, that we would necessarily hear the truth about it. Nor do I know even if such a tactic might have been employed.
But even if they were using active microwave pinging to lock a missile onto an aircraft, it can be very directional. It may only be detectable in the cone of it's emission, and anyone not directly in line with it wouldn't see the queries. They might see the responses, but not the signal that was initiating them.
But again, I don't know if any such system was used. Perhaps they used a passive system to detect the approach of the aircraft so as to time their launch.
Even if the plane's transponder was used to get a general lock, I expect the final tracking would have been the regular heat seeking method anyway.
