The PDF Chinese talk carelessly about lobbing cross strait missiles at Taiwan and that will soften up Taiwanese defense enough to make it easy for the invasion. EW drones have been around for yrs. What if the US give Taiwan a sh!tload of EW drones? The drones can loiter long enough to disrupt missiles with radar sensors. But that is not all the drones can do.
The one critical thing about radar sensors is that whenever there is an interruption in target lock, if the radar reacquire a reflection signal, the radar computer need time to reprocess the new signal to correlate with the previous signals in memory, and that reprocessing time can be up to one second. The drones can cycle on/off their transmissions to further compound the (re)targeting process. That tactic is called 'blinking' and have been around for decades.

Blinking jamming is an effective countermeasure against monopulse radar seeker. It causes line-of-sight angle to step continuously between the two angular positions through jamming resources emitting by turns. The expression of angle noise in synchronous blinking jamming and the relationship between the parameter of jamming resource and Angle Noise are analyzed on the basis of the situation of line-of-sight angle position between missile and target. The relationship between the parameter of jamming resources and Angle Noise is important in application of blinking jamming.
Airborne blinking is even worse. Given the short distance between mainland China and Taiwan, Taiwanese defense do not need one second. A few milliseconds could be just enough to make the missile failed even by just a few meters. Many hardened structures are robust enough to withstand concussions and shrapnel and will require direct hits to be destroyed or damaged. China must perform post strike battle damage assessments and the more Taiwanese defense assets survive especially after multiple salvos, the odds of delaying the invasion fleet increases, possibly even to cancelling the invasion itself. By the way, note the authors' names of the source above because I do not want to be accused of bias.
The PLA is not like the PDF Chinese members here. The PLA leadership are serious people. PLA generals are watching this war closely. How the Ukrainians uses drones will catch the PLA generals' eyes because it is not a matter if the Taiwanese defense is smart enough to use drones, but
HOW the Taiwanese defense will use drones. And the Ukrainians are giving the Taiwanese plenty of ideas.
