Thank you for posting this. The state of PAF's EW can be understood from the fact that there is no publicized EW doctrine.
I will make a bold statement: any country that doesn't have its own semiconductor fabtech backbone, doesn't really have a meaningful EW capacity.
Given this situation, EW in PAF relies on prepackaged, commercial solutions. The capabilities of PAF are limited by whatever its suppliers offer. And they are at the mercy of manufacturer compromise. If our enemies are able to compromise the OEM, they can completely circumvent our own abilities, while launching a successful attack on us. Every single piece of Western equipment is to be considered potentially compromised. If it works in war, it means the Western nations are happy to let us plat for now.
The situation with Chinese equipment is better. But it is still a matter of applying ready made solutions. In order to orchestrate successful EW - both offence and defence - one needs:
0. Understanding the fundamental nature of electromagnetic radiation itself. The full implications of Maxwell's equations and the practical outcomes when EM energy interacts with modern materials such as meta-materials. I highly doubt there is any deep understanding.
1. Understanding at the atomic level the characteristics of the semi-conductor. What are the response characteristics given incoming spectrum? How much heat will be dissipated at a given output level? How will performance degrade in various conditions? Nations with decades of actual manufacturing experience can make educated guesses about enemy capabilities in these areas. PAF has no such capability.
2. Understanding at the wafer level. What are the peculiarities of a given manufacturing process? Does it lead to bleeding effects in adjacent transistors? How does that compromise overall performance? Bold in 1 above applies.
3. Understanding at the hardware level. How does temperature, moisture, radiation affect the performance of the system? Will the signals on the data bus get scrambled under certain conditions? Are there built in hidden functionalities that are activated when a certain sequence of signals is processed? Bold in 1 above applies.
4. Understanding at the software level. What is the error rate if the detection algorithm? What patterns is it unable to identify? Are there hidden functionalities that are activated when certain sequence if signals is processed? Bold in 1 above strongly applies.
5. Finally there are aircraft maneuvering and mission planning tactics such as flying perpendicular to enemy radar's main lobe, or using obstructions to avoid detection, or using wideband jamming using OEM supplied pods etc. At least the PAF is proficient here.
But the most important is how to wage a war using EW as a tool. When enemy planes are detected in war time, do you send forth a fighter jet? Or do you mount an EW attack to disable its sensors? Why would you choose one option over the other?
Do you understand the enemy's AD measures? Are you able to accurately identify the gaps in AD coverage and take advantage? Are you able to orchestrate an effective AD? At the time of this writing, I do not have much trust, unfortunately. But one hopes that PAF will be able to deliver. The way American drones have been kept away is living testament to PAF's ability, but the general lack of scientific depth within the country puts it on very shaky foundations.
