Electronics and Radar Development Establishment

Electronics and Radar Development Establishment (LRDE) is a laboratory of the Defence Research & Development Organization (DRDO). Located in C.V. Raman Nagar, Bangalore its primary function is research and development of Radars and related technologies.

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 Ltd. and various private firms.

LRDE Radars

1. Indra series (2D radars):

Over 36 Indra-1 and Indra-2 gapfilling and 2D radars for air surveillance in service with the Indian Army & Air Force. 90 km range vs. small fighter target & over 100 target TWS in latest version i.e. Indra - 2 PC (Pulse Compression).

2. 3D CAR- Central Acquisition Radar, 150–200 km range against fighter target, 150 targets TWS, over 9 ordered by Indian Air Force & Navy. More orders likely from both services. Orders, 37 from the IAF (Rohini) and 2 from the Navy (Revathi). Likely to be more from the Navy as a Revathi has been fitted to the latest Shivalik Frigate (of which three are being built). First Rohini handed over in 2008. Another variant: 3D TCR has cleared Army trials.

3. BFSR-SR - Battlefield Surveillance Radar Short Range - over 1100 ordered and already delivered to the Indian Army. Several units exported as well. Latest variant integrated with Thermal imager developed by allied laboratory, for passive surveillance.

4.Battery Location Radar - BLR- Rajendra. Fire control radar for Akash SAM system. 3D radar, can TWS 20-64 targets, 85 km range (against small fighter target), Passive Phased Array System. Sixteen have been ordered for 8 squadrons of the Akash SAM system by the IAF. Several more orders likely from the Indian Army.

5. Wapon Locating Radar: Rajendra derivative, for locating and tracking mortars, rockets and artillery shells. Considered to be senior to AN/TPQ-37. 4 cm range. 2008 ordered by the Indian Army.

6. Long range BFSR- Medium range version for battlefield surveillance & Arty correction. In development.

7. Multi Function radar: MFCR- developed in cooperation with Thales, an AESA system for the Ballistic Missile system's fire control. Range 400– 500 km against small targets. In development, to be fielded by 2010-2012.

8. Medium Power radar. An AESA system being developed for the IAF, will be able to detect small targets at ranges > 300 km. Several systems required by IAF.

9. Aslesha 3D Low Level Light Weight Radar: 50 km, ranged, light weight semi active radar developed for the IAF, for mountainous terrain. 20 being delivered to the IAF. First prototype publicly displayed in 2008. Production to commence 2010.

10. Bharani Low Level Light Weight Radar: 40 km, 2D, 100 target TWS radar developed for gap filling for the IAF and IA. Several units on order.

11. Long Range Tracking Radar: LRTR is the primary AESA sensor for the Ballistic Missile Defence System. Able to track missiles at ranges from 500 km upwards and at speeds from 4–5 km/S, the LRTR is an advanced Indo-Israeli derivative of the GreenPine radar, and to be manufactured in India. Six to seven LRTRs to be manufactured by Indian industry. Follow on system with double the range in development.

12.AESA FCR: Active Array system for the Light Combat Aircraft & possible future applications. Currently in development. Project launched in November 2008. India's first X Band AESA system. To speed up development, LRDE will work with a development partner to leverage mature X Band Tx/Rx modules for an Active Array Unit, while it develops the ERP (Exciter Receiver and Processor, as a single LRU) inhouse.

13. SAR systems: A Synthetic Aperture Radar for unmanned aerial vehicles. Currently in trials.

14. Maritime Patrol radar: SV-2000 Slotted Array radar system developed for naval applications for Ka-31 and DO-228 usage. Trialled and cleared on Kamov helicopter and Dornier 228 aircraft. Follow on more advanced system, XV2004 with imaging capability (ISAR) in trials. Several orders likely from Navy for its Dornier 228 MPA and ALH helicopters.

15. 3 Primary radars & IFF for 3 AEW &C;: Primary S-Band AESA radar for the DRDO Airborne Surveillance project. Range of around 200–300 km (dependent on mode) vs. small size manoeuvering fighter target. To be productionized by 2012. Medium range systems (6-8) to follow.

16.FOPEN radar: New project announced in 2009. Foliage Penetration radar intended to track movement of men and vehicles under foliage. To be fitted on aircraft, range of approximately 30 km. Intended to be developed by 2012-13.

17.Low Level Transportable Radar or LLTR: New active aperture array radar (AESA) with a range of around 150 km. To be developed by 2012-13. Project formally launched in 2008, with work on prototype underway in 2009. Like the Medium Power Radar, the LLTR will be a fully open system, able to interface with a variety of weapons systems and C3I equipment, allowing for greater flexibility and versatility.

Several other projects have been delivered including LCA subsystems and radar C3I for the IAF.
