Phazotron JSC's Airborne Radars

I'm enclosing above the posters of the new-generation radars being offered by Russia's Phazotron JSC. As they reveal, only the Zhuk-AE is of the AESA-type. The words phased-array in the posters mean PESA.--Prasun K Sengupta

not all these radars r pesa but some of them r aesas

top pic is of pesa
second is of aesa

go to more info go to

first russia developed zhuk ae prototype for mig 35 shown on aero india2007,it had 680 t/r modules

its larger version will b
zhuk ae35 with 1068 t/r modules
that will b the production radar for mig35 offered to india

largest version zhuk ase is for
su30 series and has 1630 t/r modules greater than any other aesa radar in the world ,this radar is offered to china for upgrade

I specifically asked Phazotron JSC's General Designer last December what was the difference between 'phased-array' and APAA. He clearly told me that 'phased-array' was the equivalent of PESA, and was similar to the NO-11M Bars and Bars-29. The only AESA they were gearing up to series-produce was the Zhuk-AE APAA. The Zhuk-ASE that you mention is still in the technology-development stage and therefore no proper brochures or posters of this radar have been revealed to date. I've only seen artist's engineering drawings of this radar so far.

one thing i want to know that russians brouchers which tell the radar ranage of detection against meter square of target and the detection ranges against ground targets

no such thing has been seen about american aesa like
apg70,80,81,77,63,or amsar,
cpater e,or rbe2 peasa and future aesa

Mr. Prasun,

Can I have an update on DRDO's MMR? Sorry if I missed the boat but I'm banging on your patience to get my answer.

To Anon@7:26AM: The RCS detection parameters/performances of all AESAs are almost the same, as the laws of physics governing the performance of such radars is identical. But if you look carefully at the posters of Russian radars (mechanically-steered, PESA or AESA) and see their MTBF figures, you will realise that Russian radars have a long way to traverse in order to match their European and US counterparts. For instance, a radar like ELTA's EL/M-2032 has a guaranteed MTBF of 350 hours, while that for the Zhuk-ME does not exceed 200 hours.

To Anon@10:40AM: The MMR project was screwed up largely by HAL, and not LRDE. The entire project was mismanaged. Even the flying testbed--an Avro HS-748--was the wrong choice. But there is always a ray of hope and what's now happening is the back-end of the MMR (comprising all LRUs excluding the antenna array and its mechanically steered mechanism) is being integrated with the front-end of the ELTA EL/M-2052 AESA and the resultant weight-budgeted MMR will go on board the Tejas LCA. Prototypes of such MMRs have already been test-flown on an IAI Westwind jetliner/flying testbed and will soon be flight-qualified on one of the Tejas LCA LSP testbeds.

if elta2032 has MTFB of 350 then y india choose ZHUK ME for mig29 upgrade insted of elta2032

y india choose kopyo radar on
mig21bison upgrade

and for mig21 upgrade y kopyo radar has r77 missile capability and y elta2032 radar only has capability of derby

prasunji, PESA stands for Passive Electronically Scanned Array.....when u say 'phased array', it simply refers to the arrangement of the radiating elements of an array (ie a radar antenna )
