Где почитать о Doppler radar clutter notch?

Хочется познакомиться с какими-нибудь выкладками о теории этого явления и о том, как используется этот эффект в ВБ.

Нашел я пока очень мало:

This physical phenomenon is a direct consequence of the low-Doppler characteristics of the targets and results in interfering fading effects that seriously affect both tracking performance and track continuity.

THE SCENARIO in which the Su-30 "always" beats the F-15 involves the Sukhoi taking a shot with a BVR missile (like the AA-12 Adder) and then "turning into the clutter notch of the F-15's radar," the Air Force official said. Getting into the clutter notch where the Doppler radar is ineffective involves making a descending, right-angle turn to drop below the approaching F-15 while reducing the Su-30's relative forward speed close to zero. This is a 20-year-old air combat tactic...
