Ok, let me go by these very figures. 350kms broadside for fighter sized targets. The AEW&C would not be flying any closer than 100kms(and thats the minimum limit) close to the border. You still get 250kms. If PAF is extra cautious, it goes further down, and mind you. Its far better to be safe with AEW&C than take risks. IAF itself wont be flying closer than 100kms. In anycase they already use Aerostats near the western border with ranges already around 350kms. More are being bought.Lets see...
I don't see where it has validated your claims. According to this source Erieye can monitor a sector with angle 150 degrees and radius 350km on each side of the aircraft, therefore if it is flying parallel to the border, ~50km away from it, it can monitor fighters up to ~300km into India. This way it doesn't even need to search both the sectors, just the sector over India. We know that the phased array radar's performance decreases as the angle increases, so at angles smaller than 150 the detection range for fighter size targets will be greater than 350km. The area of the sector that is 90 degrees (perpendicular) to the radar will have higher range than 350. If I'm wrong, please show me where and how I'm wrong.
Where i got it is irrelevant. AESA's can be made to operate in different modes. Regular search is when the radar is searching the maximum degrees of search possible. However, when the operators get specific info about a threat in a particular sector, the aesa can be redirected to search only in that sector. All the T/r align their beams along that sector thus giving a greater range in that particular sector. That is extended, sector specific search. Which the Erieye would employ for fighter detection at 350kms at a 150degree angle broadside, both sides. Erieye has 360degree detection. However it doesnt mean that if you further reduce the searching angle, the detection goes further up.Why do you keep talking about "extended search modes not used in regular ops" if you can't show me where you got that info?
