Just after that the article dismiss that idea:The article stated "The claim reveals that the Top Pair radar couldn't distinguish the Neptunes flying over the sea from the crests of the waves due to the stormy weather."
I'd be surprised if this was the case. Even my 4' open array radar has anti sea clutter capability. Surely the Russians would have some pretty sophisticated systems that would have the capability to filter interference from sea-state. I think the radar operators just weren't paying attention. Or for some reason had turned off alarms/alerts possibly due to false alarms received to that point.
"These claims lack a solid basis, as the ship in question is a cruiser with good air defense capabilities."
And further below elaborate why dismessed it:
"On the other hand, it is not reasonable to compare a search radar (MR -800 Voshkod/Top Pair) with a tracking radar (3P41 Volna). Prior to the introduction of fixed face AESA radar technology, warships use search radars to detect air contacts. If the air operator believes the contact is a threat, he/she forwards the contact to the tracking radar to illuminate the target for surface-to-air missiles. Tracking radars are not there to "detect" a target, but to illuminate the contact that has already been detected by the search radar. These two types of radars are pieces of a puzzle that serve the same purpose.
Also, these radars may have some blind sectors due to the structure of the ship, but there are other radars to cover the blind sectors, just like the Slava class cruisers have more than one radar (Top Dome, 2xPop Group, 3xBass Tilt, Kite Screech fire control radar). So this ship can continuously track the air contacts, even if the contact moves into the blind sector of the radar, the operator can forward the contact to another tracker and keep following.
As mentioned above, the sea state was not tough to hide the sea-skimming missile from radar. Even if there was a tough sea, the search radar would detect it, but it might have some difficulties in maintaining the contact due to the sea clutter. When the sea state is high, the missile's flying altitude gets higher because the missile's altimeter adjusts the altitude from the wavetop.
Slava-class cruisers are equipped with the 4xRum Tub electronic support system, which can detect Neptune anti-ship missiles' radar seekers. After detecting the radar seeker, the ship would have about 2 minutes to defend against the missile. In addition, the Moskva was armed with 6x30mm/AK630 close-in weapon systems that have their own radar and are capable of detecting and engaging the incoming missiles themselves."
