'''Electronics and Radar Development Establishment''' (LRDE) is a laboratory of the [[Defence Research and Development Organisation|Defence Research & Development Organisation]] (DRDO), [[India]]. Located in [[CV Raman Nagar|C.V. Raman Nagar]], [[Bengaluru]], [[Karnataka]], its primary function is research and development of [[radar]]s and related technologies.<ref>{{cite web|url=http://www.drdo.org/labs/lrde/index.html |title=Electronics and Radar Development Establishment |access-date=2008-02-08 |archive-url=https://web.archive.org/web/20080131205942/http://www.drdo.org/labs/lrde/index.html |archive-date=2008-01-31 |url-status=usurped }}</ref> It was founded by [[S. P.

LRDE is sometimes mis-abbreviated as "ERDE". To distinguish between "Electrical" and "Electronic", the latter is abbreviated with the first letter of its Latin root (''lektra''). The same approach is used with for the [[DLRL]]. The LRDE is India's premier radar design and development establishment and is deeply involved in Indian radar efforts. Its primary production partners include [[Bharat Electronics|Bharat Electronics Limited]] (BEL) and various private firms like [[Mistral Solutions]] in [[Bangalore|Bengaluru]], Astra microwave in [[Hyderabad]] and Data Patterns in [[Chennai]].

*[[DRDO AEW&CS|'''Netra AEW&C''']]: The AEWACS aircraft has an [[active electronically scanned array]] (AESA) primary radar with IFF. The system will also have ESM (Electronic Support Measures) and CSM (Communications Support Measures) ability. Datalinks to network the AEW&CS with fighters, and ground-based control systems will also be provided, as will be the SATCOM (Satellite Communication System). The aircraft will also have a comprehensive self-defence suite. The avionics suite will be linked via a datahandling system, controlled by Mission computers.

*'''Air Defence Tactical Control Radar''' (ADTCR): 3D AESA radar. It is developed by  Electronics and Radar Development Establishment (LRDE),  a laboratory of  the [[DRDO]]  which is being developed for Indian Army.  Air Defence Tactical Control Radar (ADTCR)  is used for volumetric surveillance, detection, tracking and friend/foe identification of aerial targets of different types, and transmission of prioritised target data to multiple command posts/ weapon systems. The radar is capable of detecting very small targets and low flying targets. It is capable of tracking 100 aerial targets at a time. It has a range of 500&nbsp;km (maximum).

Apart from the above, the DRDO has also several other radar systems currently '''under development''' or in trials. The systems on which publicly available information is available include:

* [[Uttam AESA|'''[[Uttam AESA]]''']] is an indigenously developed active electronically scanned array (AESA) fire control radar. It is being developed for the [[HAL Tejas Mk2|Tejas Mk2]] and [[HAL Tejas|Mk1]] and also other aircraft upgrades such as the IAF's [[Sukhoi Su-30MKI]], [[Mikoyan MiG-29|MiG-29]] and [[Mikoyan MiG-29K|MiG-29Ks]]. Hardware has already been realised for this radar which has a range of 100&nbsp;km against small fighter sized targets and rooftop testing is underway. Though the [[Uttam AESA]] currently weighs 120&nbsp;kg which is some 40&nbsp;kg more than the current MMR, there will be no problem in integrating it with the LCA Mk-II which can easily carry a radar of this weight.<ref>{{cite web |url=http://ibnlive.in.com/blogs/sauravjha/2976/65448/the-radiance-of-tejas-a-bright-prospect-for-make-in-india.html |title=Saurav Jha's Blog : The Radiance of Tejas: A bright prospect for 'Make in India' |website=ibnlive.in.com |access-date=17 January 2022 |archive-url=https://web.archive.org/web/20141224190232/http://ibnlive.in.com/blogs/sauravjha/2976/65448/the-radiance-of-tejas-a-bright-prospect-for-make-in-india.html |archive-date=24 December 2014 |url-status=dead}}</ref> It is a 3D radar for fighters, a MMR follow on, the APAR project aims to field a fully fledged operational AESA fire control radar for the expected Mark-2 version of the [[Light Combat Aircraft]]. This will be the second airborne AESA program after the [[Airborne early warning and control|AEW&C]] project and intends to transfer the success the DRDO has achieved in the Ground-based radar segment to airborne systems. The overall airborne APAR program aims to prevent this technology gap from developing, with a broad based program to bring DRDO up to par with international developers in airborne systems: both fire control and surveillance.
