Sorry to bring up an old topic. I came across an article by the "The Drive" where there was a refutation given by the Authors on India's claim of shooting down an F-16. The article's Authors are Joseph Trevithick And Tyler Rogoway. In the article, they make a mention about the radar images which the Indian Airforce had released to validate the F-16 kill.
So they said this.
"Without having more data and context, we have no way of knowing conclusively that the contact disappeared and never reappeared or that it was an F-16, to begin with. Electronic warfare and the limitations of the airborne early warning and control system could have been factors, as well. The mountainous terrain and other ground clutter may have masked the Viper's radar signatures temporarily and the fighter could have dropped into the "doppler notch" of the airborne radar system."

So what do fellow members have to say about this "Doppler notching" drama? A lot of Pakistanis, and even westerners are using this to counter the radar images which were made public by the Indian Airforce.
That day, on 27th February 2019 when Swift Retard happened, we had several eyes in the skies. For e.g the Su-30MKI with its Bars PESA radar, the PHALCON AWACS. I think the PHALCON AWACS's radar is AESA.

@cyclops said that Modern AESA radars are immune to Doppler notching.
@mist_consecutive said the same and added that AESA radars and the PESA radar of Su-30 MKI is immune to Doppler notching. Further clarification would be appreciated.
