there is really no better primary sources that are more recent, the F-4 tacman already has them retracted and moved to the secret tacman supplement.
And also, even modern radars would look like that when getting jammed, no amount of signal processing will grand you a usable signal if the jammer signal is stronger than the return signal.
That is debatable. For example “pulse compression” is even designed to work with its signal being “quieter” than the noise and uses a matched filter to get its signal back. That’s why it’s also called “silent radar”, because you can’t really detect the signal without knowing its structure as long as the pulse isn’t stronger than the environmental noise. It’s even used for civilian boat applications (not for LPI but better detection/signal-to-noise-ratio). Only downside is that the electronics and software are much more complex and therefore expensive.
DSSS (Direct Sequence Spread Spectrum), which is used in military communications (and even GPS, WiFi, DECT, etc.), uses a similar principle by spreading a narrow band signal over a wide band.

Jamming is the most effective if you can jam a narrow band with high energy while the jammend device can’t evade to other frequencies. If you want to jam a wider band you have to roughly put in the factor more energy the band is wider (if you jammend 1 MHz with 1 kW, you need 4 kW to jam 4 MHz bandwidth to keep the same jamming strength up). Pulse compression works by “stretching” the signal from narrow band to a wider band (e.g. 1 MHz to 32 MHz) while keeping the same overall energy and using filters to decompress the return signal.
F/A-18A radar (so TWS+ capability being cutoff?) had absolutely no issues finding and tracking Tu-95, though STT was bit unstable, constantly altering speed and direction.
Any launched non datalink Sparrows were flying as if lacking radar return, self detonating 20s later.
Mig-29 radar couldn’t find nor track B-52, but could grab IRST lock, then by switching to radar, which immediately entered memory mode you could launch R-27ER. Then by alternating IRST and radar you could update missile IOG via datalink, in steps. Likely good enough guidance against bomber sized target.

No need to sound so rude about it.
It was extended to the 6’th so it ended 3 days ago:
They plan to do another test soon:
