Periodic updates are not forthcoming. News comes out only when program crosses some major milestones. Fixed your post for you sire ;)

Everybody is researching conformal arrays. Everybody. Raytheon claims it can deliver conformal arrays one inch thick to be mounted on the underside of UAVs once the technology is sorted out. Boeing was proposing aesa modules as a part of skin and structure for futuristic super hornet. Probably...

No one has fit AESA arrays over a curved surface yet. The complexities of returning signals and assimilating data from them would be a very complex task, hence aesa arrays are flat, even though curved arrays would solve a lot of problems.

The bandwidth required to pump 'raw' data is exceptionally high and the satcom bandwidth costs even higher. It can be done via line of sight links, but why would the airforce want to operate two aew&cs in the same sector ? Only processed data is transferred over satcoms, where it will be fused...

A) Google it. OR B) Read a couple of pages in this thread. It won't kill you.

An update on AEW&C program. A couple of years back it was reported in a market study AESA module manufacturer about an AESA radar developed in association with CABS (centre for air borne systems) somewhere around 2010:-...

Thank you Sayareakd for the comprehensive collection of info.

re: Indian EMB-145 AEW&C Making the hardware is the easier part. The Indian BMD system is two tiered featuring an LRTR (L-band) and a MFCR (S-band). We have recieved considerable ToT for S-band radars ( from GS100 LLTR tot from thales to be used in Ashwini LLTR and from EL-2284 from elta for...

re: Indian EMB-145 AEW&C That figure is straight from the manufacturer. See the link I posted earlier, it has tons of nuggets on a lot of radar programs.

re: Indian EMB-145 AEW&C Drdo's aew&c uses S-band Active Aperture Array of 1244 elements using 100W TR modules . The FSR-890 uses 200 T/R modules of undisclosed power rating.

re: Indian EMB-145 AEW&C Not 1996, for the first Indian patent on AESA T/r modules was filed in 1998 :P This image is quite ancient though, for the report on ACIG was prepared by the late B Harry. The lower image featuring an s-band package consisting of two t/r modules has been surpassed...
