Best Answer

Notch maneuver is when an aircraft being tracked by a pulse Doppler radar (whether ground or air intercept radar from an adversary aircraft) flies perpendicular to the radar to escape detection and tracking. Since Doppler radars use Doppler shift to determine its target's velocity and whether it's flying away or inbound, when the targeted aircraft flies perpendicular relative to the radar, it loses it's Doppler shift, thus, the radar ignores it thinking that it's a stationary target such as mountains and etc.
