The only radars that are in the Army section of the LRDE website, which we don't have names/ data on are:
FOPEN (Foliage Penetration)
GPR (Ground Penetration Radar)
MMSR (Multi Mission Surveillance Radar)
We also know LRDE is working on TWIR (Through Wall Imaging Radar)
Lets work through these options.
1.We know its not the GPR. That was mentioned separately.
2. Is not the FOPEN (IMHO) because, the antenna array is usually very different. See:http://img12.imageshack.us/img12/9632/tp864.jpg
In fact DRDO was supposed to be collaborating with SAAB on adapting CARABAS. For further confirmation, check FOPEN from LM, similar antenna arrays mounted in a long pod. By their very nature, these radars are mounted on aircraft.
3. As to MMSR - doubt that because an ideal MMSR would be high powered enough to detect arty rounds, mortar rounds etc - meaning vehicle mounted, larger antenna array. (e.g. http://www.iai.co.il/sip_storage/FILES/9/38029.pdf
4. Is not a TWIR - those are hand held/man portable much smaller units (http://www.endoacustica.com/immagini/prisma_370x363.jpg
5.Looking at the stuff that is there on the side - the central unit electronics in a cradle behind the antenna, plus the 4 legged base, power supply/UPS etc besides on the ground - it seems very similar to Aslesha. http://1.bp.blogspot.com/-Doi6jByv4js/T ... poster.JPG
Also, the visitor is Gen from the Army Air Defence.
Aslesha is also being modified for the IAF (a higher power variant on a truck), is on offer for the Navy (light ships, will require stabilization - like L&T did for Revathi) and for ATC (Air Traffic Control) for civilian operators.
Note, the simpler 2D Bharani LLLWR was developed for the Army AD as well and is being procured by them. After the Aslesha cleared trials for AF in Ladakh/Leh, 21 are being made for the AF.
Hence, a variant for Army Air Defence is not implausible.
