*[[Central Acquisition Radar (3D-CAR)|Central Acquisition Radar]], a state of the art planar array, S Band radar operating on the stacked beam principle. With a range of 180&nbsp;km against fighter sized targets, it can [[track while scan]] 200 of them. Its systems are integrated on high mobility, locally built TATRA trucks for the Army and the Air Force; however it is meant to be used by all three services. Initially developed for the long-running Akash SAM system, seven were ordered by the Indian Air Force for their radar modernisation program, and two of another variant were ordered by the [[Indian Navy]] for their [[INS Kamorta (P28)|P-28 Corvettes]]. The CAR has been a significant success for radar development in India, with its state of the art signal processing hardware.<ref>{{cite web|url=http://www.acig.org/artman/uploads/os_car_001.jpg |title=JPEG image of the 3D CAR, image copyright Acig.org |access-date=2010-08-31}}</ref><ref>{{cite news|url=http://economictimes.indiatimes.com/PoliticsNation/IAF_going_through_stage_of_modernisation_Major/articleshow/3705906.cms |title=IAF modernisation |newspaper=The Economic Times |publisher=Economictimes.indiatimes.com |date=2008-11-12 |access-date=2010-08-31}}</ref>

*[[BEL Battle Field Surveillance Radar|BFSR-SR]], a 2D short range [[Battlefield surveillance radar|Battle Field Surveillance Radar]], meant to be man-portable. Designed and developed by the LRDE, the project was a systematic example of concurrent engineering, with the production agency involved through the design and development stage. This enabled the design to be brought into production quickly.<ref>{{cite web |author=Source |url=http://finance.indiainfo.com/news/2005/02/08/0802aerobel.html |title=BFSR orders and export push |publisher=Finance.indiainfo.com |date=2005-02-08 |access-date=2010-08-31 |url-status=dead |archive-url=https://web.archive.org/web/20090110195132/http://finance.indiainfo.com/news/2005/02/08/0802aerobel.html |archive-date=2009-01-10 }}</ref><ref>{{cite web|url=http://www.hinduonnet.com/holnus/001200708060340.htm |archive-url=https://web.archive.org/web/20071013161633/http://www.hinduonnet.com/holnus/001200708060340.htm |url-status=usurped |archive-date=2007-10-13 |title=BEL to export anti-infiltration radar to Indonesia |publisher=Hinduonnet.com |date=2007-08-06 |access-date=2010-08-31 }}</ref> [[File:BFSR-SR with thermal imager.JPG|thumb|[[BEL Battle Field Surveillance Radar|BFSR-SR]]]]

*[[Swordfish Long Range Tracking Radar|Long Range Tracking Radar]]: The LRTR a 3D [[Active electronically scanned array|AESA]] was developed with assistance from [[Elta Systems|Elta]] of [[Israel]], and is similar to Elta's GreenPine long range Active Array radar. The DRDO developed the signal processing and software for tracking high speed [[ballistic missile]] targets as well as introduced more ruggedisation. The radar uses mostly Indian designed and manufactured components such as its critical high power, L Band Transmit-Receive modules plus the other enabling technologies necessary for active phased array radars. The LRTR can track 200 targets and had a range of above {{convert|600|km|mi}} and can detect [[Intermediate-range ballistic missile|Intermediate Range Ballistic Missiles]]. The LRTR would be amongst the key elements of the Indian ABM system.<ref>{{cite web|url=http://www.hindu.com/2005/04/15/stories/2005041509810400.htm |archive-url=https://web.archive.org/web/20050420021916/http://www.hindu.com/2005/04/15/stories/2005041509810400.htm |url-status=dead |archive-date=2005-04-20 |title=Details of LRTR from 2004 |date=2005-04-15 |work=[[The Hindu]] |access-date=2010-08-31}}</ref>

* 2D Low Level Lightweight Radar (LLLR) "Bharani" for the Army. The LLLR is a 2D radar with a range of 40&nbsp;km against a 2<math>m^2</math> target, intended as a gapfiller to plug detection gaps versus low level aircraft in an integrated Air Defence Ground network. The LLLR makes use of Indra-2 technology, namely a similar antenna array, but has roughly half the range and is much smaller and a far more portable unit. The LLLR can [[track while scan]] 100 targets and provide details about their speed, azimuth and range to the operator. The LLLR makes use of the BFSR-SR experience and many of the subsystem providers are the same. Multiple LLLRs can be networked together. The LLLR is meant to detect low level intruders, and will alert Army Air Defence fire control units to cue their weapon systems.<ref>{{cite web|url=http://media.bharat-rakshak.com/aero/main.php?g2_itemId=1355 |title=LLLR Specifications |publisher=Media.bharat-rakshak.com |date=2007-01-18 |access-date=2010-08-31 |url-status=dead |archive-url=https://web.archive.org/web/20071021103105/http://media.bharat-rakshak.com/aero/main.php?g2_itemId=1355 |archive-date=2007-10-21 }}</ref>
