At the very least we have to make sure our AWACS aircraft can detect this fighter at some distance and from certain angles. True it may be a reduce distance due to EW jamming, but PAF needs to find a way to make sure the Erieye can detect the Rafale as early as possible. Perhaps a “Lock-on-Jam” function to detect not the exact location but the vicinity of a target and use new algorithms to over power the enemy’s jamming, and detect the Rafale. It may require an upgrade, but if the PAF can demystify the Rafale it will make the IAF lose the perception that they should try more adventurism. Upgrading the Erieye also plays on the Indian inferiority complex vis a vi White people.
The Rafale’s spectra system works on the Doppler principle, if I’m not mistaken. One possible way to country this is using multiple Aesa radars to generate different beams from different angles, tens if not hundreds of km apart. Such as wo Th that new Turkish HALE drone equipped with an AESA radar, EW, and modern comms. Then with the use of triangulations and large passive arrays and large arrays operating in different bands on the ground, data can be fused to detect not just to detect the Rafale but even more modern planes.
If the PAF in an exercise with Qatar can quietly release that the Erieye, with a Global Eye (GaN) and new algorithms upgrade was able to detect the Rafale at 100’s of Kms out, they will be forced to rethink their capabilities, hopefully leading to forces inside India recommending their government doesn’t try anything. Deterrence being maintained, conventionally.
