Notch radar.

The notch is effective when the radar is looking up or down because it is applied to all returns. A hovering helicopter, regardless, of the height above ground would normally be filtered out of the radar, however, as someone has mentioned radar returns from the rotating blades are usually large/fast enough that regardless of relative velocity ...Digital notch filters find extensive use in various fields such as automatic control, biomedical engineering, communication and radar.

Notch while being lower than the enemy. If he's got a non pulse doppler radar, then he will be distracted with ground clutter. At least until he gets near, after which you'd have to do some maneuvering. If he's got a PD radar, then his radar will mostly see you as a ground object as your velocity along his flight path will be zero.

If you're using the aim7d, my advice is to not even bother. I have found them to be nearly useless, where as the aim7e are decent, but give them a go if you want. I have the radar bound to my numpad, in the order that they are top to bottom in the controls menu (num 0 turns it on and off, num 1 switches mode, etc).The Irbis-E is marketed as having a 350 km range against 3 m^2 target while in reality that’s only in cued-search in a tiny FoV. What’s rarely stated is that in normal volume search that range shrinks down to 200 km. More importantly, Su-35’s radar has a maximum targeting range of 250 km – even for a B-52 like target.A Bow Echo is a type of linear multicell characterised as a bow-shaped (or concave-shaped), 20-120 km line of convective cells.
