Are moving relatively slowly or stationary, and so the radar will simply filter them out. the wider you make those kind of velocity gates in terms of what the radar is looking at and what it's disregarding, the more clutter you'll have to deal with, and so the better processing you'll require in order to get usable results for military purposes. what's happened since the chinese spy balloon incident in the us is that the us appear to have reprogrammed a lot of their surveillance radars for air defence purposes with much, much wider velocity gates. so, they're suddenly seeing a lot of sort of f...

False returns if you're looking for something like aircraft or missiles, which would be the normal military things that they're trying to track, they will filter out and drop anything that is moving outside of a given range of speeds. so, this is why military radars, for example, are able to, most of the time, disregard things like clutter from the ground, reflections from trees and reflections from birds, clouds, depending on the frequency of the radar — because those objects are moving relatively slowly or stationary, and so the radar will simply filter them out. the wider you make those k...

This is where we're still talking. you've got a tornado warning right now right there along the alabama georgia state line, and you've also got some strong thunderstorms, lots of cloud to ground lightning and some damaging winds that could still bring down some trees and power. winds from the carolinas across the southeast. also this area up here across portions of west virginia, pennsylvania, where he also could have some strong thunderstorms there. one thing to note, however, at least across the southeast is this front is going to become stationary, meaning more rain showers will continue to...

It's a difficult one. so in terms of dealing with them, first of all, there's the immediate question of what altitude are they at and what speed are they drifting at, because the primary means for militaries to detect flying objects is radar. and radar works essentially by bouncing energy off objects and reading the returns. but in order to not get endless false returns if you're looking for something like aircraft or missiles, which would be the normal military things that they're trying to track, they will filter out and drop anything that is moving outside of a given range of speeds. so thi...
