Interesting thread found on reddit that Su 30mki radar is hybrid AESA-PESA radar.
was reading a bit about radar systems, and this is what I saw about the Bars radar on the MKIs.

N011M is used on
Su-30MKI, and the contract for the N011M radar has three stages. The initial MK1 software was tested in 2002 and supplied with the first Su-30MKI deliveries. India was supposed to build both programmable
signal processors and data processors under project "Vetrivale" to replace the original Russian components, but failed to do so within the required time frame, so MK2 still used the Russian equipment. In 2004, India delivered Vetrivale radar computer based in the i960 architecture. It's worth noting that N011M is not simply a PESA, but instead, it's a transition between PESA and AESA in that it adopts technologies from both: each
transceiver on the antenna array of N011M has its own receiver amplifier, which is the same as AESA, and with noise level of 3dB, which is also in the same class of AESA arrays. However, for transmitting, N011M uses PESA technology in that a single Chelnok
traveling-wave tube is used for EGSP-6A transmitter. There are three receiving channels for N011M.
N011M has a search range of 400 km and a tracking range of 200 km, with 60 km in the rear in the air-to-air mode. Detection range fighter type MIG-29 in area of review of over 300 sq. deg: - on towards course - up to 140 km; - in pursuit of - up to 60 km.
This was upgraded to Irbis-E which I think Russia offered to China.
Interesting bit about the
https://en.wikipedia.org/wiki/Irbis-E
It can detect a target with
radar cross-section(RCS) 3m2 at up to 400 km, (towards each other, in an area of 100 square degrees)
[3][4] while a target with RCS 0.01m2 at up to 90 km
This would mean an F-22 will remain virtually invisible to these radars.
Sometime back Vishnu Som mentioned it that India was looking at Irbis-E for MKI upgrade.
- The radar India will be looking to upgrade the jet with would be the Irbis-E ... which can can detect and track up to 30 airborne targets at one time at ranges near 350~400 kilometers, and attack up to 8.
