Seems the su-30s will get new engines and radars by the end of this year.

“
The upgrade will boost the fighter’s combat capabilities: it will increase the range of detecting and identifying air targets and furnish the plane with new precision weapons to hit air, ground and sea targets at a range of several hundred kilometers.”
“After completing the work on the Su-30SM upgrade, changing the layout of the onboard radio-electronic equipment to make the Su-35 and the Su-30SM more standardized and thus cut the cost price, and standardizing the airborne weapon systems, this may breathe a new life into the plane,” the vice-premier said.
TASS reported in September 2018 that during their upgrade the Su-30SM fighters would also get AL-41F-1S engines mounted on the Su-35 planes. It was also reported in January 2019 that the trials of the modernized Su-30SM multirole fighter jets were expected to be completed before the end of 2019.
I have nothing but questions its like a new discovery to me leads to more questions.
I have realized that in total the aircraft has 2,238 T/R modules if sides were included and with its own ECM arrays in back the aircraft can basically be like a giant a$$ receiver.
The question I got is lets say there is a noise level of -145 dBW and -100dBW and there was a target that was 100kms away. Would the one with the lower noise level be less off target than the one with the higher noise level? Stealthflanker’s calculator had me experimenting with theoretical tracking ranges of the 64 modules on a k-77m missile. I was testing out what range the missile has to get within an aircraft to use its own host rader and even find out how wide the radar beam of a host radar system is to be to determine how far off target in can or cant be.
I swear this will be my last time asking a question regarding the AESA calculator. I do not know if its a user error on my part or this sheet does not calculate RCS distance when narrowing or widening beams.

The F-22’s radar range is only [officially] described as being more than 100 mi. However, it’s thought to be closer to 125–150 mi., which is much further than the standard F-15’s 56 mi. radar range. New, active electronically scanned radar technology – optimized for digital output – is expected to soon push next-generation radar [the AN/APG77v1] ranges, in narrow beams, out to 250 mi.
The APG-77v1 with newer
modules provides a range of 250 mi (400 km) or more; this is believed to be possible due to the use of more narrow beams
and can cue radar emissions to be confined to a
(down to 2° by 2° in azimuth and elevation) to increase stealth.
Even the Nebo-M with 360 degrees for a 1m2 target shows 480km but narrow the beam to 90 degrees that distance increases to 510kms.
Is it too much trouble to ask you if there is a possibility you could update an excel sheet calculating the RCS distance by either widening or narrowing azimuth radar beams(Or I just do not have the know how or its a screw up on my part)? For example I put 2000 T/R modules with 10 watts for modules, than put 1m2 for the target RCS, without changing the other properties(assuming this is the an/apg-77v1 calculations). So for horizontal beam I put 120 degrees, and vertical I put 12 degrees, 90% lock on I got 217kms. than narrowed the beam for both 2 by 2 degrees I got 179kms while the sources I have regarding the SU-35 and F-22 tell me if I narrow my beams I spot the same target more far away. Is there another calculation to do this in which you have for your sources, if so is it possible to update an excel sheet(while keeping it simple and stupid for users like me) by the use of narrowing beams and seeing targets more far away?
