Radar is a technology which detects objects by bouncing radio waves off of them. It was brought into widespread use during the second world war as a way of discovering oncoming aircraft. However, low-flying aircraft could not be detected by radar, hence they flew "under the radar", that is, low enough not to be detected. Something which is "under the radar" is therefore something which cannot be detected. Often it is used for something which is too small or apparently insignificant to be detected by whatever means are being used to detect it.
The more common phrasing is "under the radar" and it means to avoid detection.
Frequency agility is the changing radar frequency rapidly and continuously to minimize jamming effect or enhance the target resolution and hit per scan. where as frequency diversity is a method to couple two radar transmitters to a single antenna simultenously to increase the range of radar in terms of coverage.

It depends. Flying below radar is usually flying below the equipment used to detect things on radar. It could be a very high tower, hundreds of stories off of the ground, or it could be a satellite just a couple stories off of the ground.
