Do you have any practical experience with secondary surveillance radars? If you did, you'd realize that a person doesn't need a knowledge of advanced physics or electromagnetism to understand why the information in your post is largely irrelevant to this discussion. Not only have I taken an (or even a few) "upper division physics" classes, I graduated from one of the top engineering schools in the nation, took many semesters of electrical engineering, weapons systems engineering and related topics. But more importantly, I have spent the last 16 years of my life working daily on a practical level with exactly what we are talking about in this thread. You obviously have not. If you had, you would realize why IFF transponder signals do not bounce off of other objects (near or far) and create falls secondary returns for systems like ATC ASR radars, or the PASSUR system. Here is a suggestion. Do some reading on the difference between primary radar and secondary radar. Then do some reading about the technology used by the PASSUR system. And stop assuming that government agents are hiding behind every story to pull the wool over your eyes.

I don't assume that. Why did you write that?
