Radar notching.

In order, to eliminate ground returns the pulse-doppler radar uses a filter around the 0-speed return frequency, this is called a notch. Since the majority of ground returns have 0-speed, this allows the radar to filter out 99% of ground returns. The size of the filter dictates how sensitive the radar is ground returns and slowing moving.

Unlike Continuous Wave radar (or normal radar) in the game, it is immune to Ground Clutter which appears as a smearing effect on the radar when flying low or facing the ground. This smearing effect means that the radar cannot search (and hence track ... Enemy aircraft turn very slowly so you can anticipate when they can notch PD radar and avoid it for testing. Using PD and wings level, I easily lock onto enemy nose to nose, same altitude 15km out. One second later, I begin slowly rolling the aircraft to the left or the right and the radar loses lock close to 20 degree bank angle.

No. Notching doesn't reduce your radar return or anything, and 'normal' radars don't filter out stationary objects. It shouldn't accomplish anything in that case. However, non-PD radars are generally easy to foil by flying low. They can't pick planes out of ground clutter most of the time.We would like to show you a description here but the site won’t allow us.

When people talk about notching they nearly always mean the getting yourself into the doppler notch (by flying perpendicular to the attacking aircraft), as getting into ...It enables the radar to look down against ground clutter by using the Doppler effect to filter out the ground and only pick up contacts moving at aircraft-like speeds. But in doing so, it creates blind spots. Planes flying perpendicular to the radar (notching) will disappear, as will most planes flying directly away.The issue with notching is that it works while you're in the notch. This is how it works in falcon as well.
