The DRDO's initial projects included short range 2D systems (Indra-1), but it now manufactures high power 3D systems, airborne surveillance and fire control radars as well. The publicly known projects include:

*[[Indian Doppler Radar|INDRA]] series of 2D radars meant for Army and Air Force use. This was the first high power radar developed by the DRDO, with the Indra -I radar for the Indian Army, followed by Indra Pulse Compression (PC) version for the Indian Air Force, also known as the Indra-II, which is a low level radar to search and track low flying cruise missiles, helicopters and aircraft. These are basically 2D radars which provide range, and azimuth information, and are meant to be used as gapfillers. The Indra 2 PC has pulse compression providing improved range resolution. The series are used both by the [[Indian Air Force]] and the [[Indian Army]]<ref>[http://www.bharat-rakshak.com/LAND-FORCES/Army/Images/0145.jpg Indra-I radar, image copyright Bharat Rakshak] {{webarchive |url=https://web.archive.org/web/20090226074051/http://www.bharat-rakshak.com/LAND-FORCES/Army/Images/0145.jpg |date=26 February 2009 }}</ref>

*[[Rajendra Radar|Rajendra fire control radar]] for the [[Akash missile|Akash SAM]]: The Rajendra is a high power, [[Passive electronically scanned array]] radar (PESA), with the ability able to guide up to 12 Akash SAMs against aircraft flying at low to medium altitudes. The Rajendra has a detection range of 80&nbsp;km with 18&nbsp;km height coverage against small fighter sized targets and is able to track 64 targets, engaging 4 simultaneously, with up to 3 missiles per target. The Rajendra features a digital high speed signal processing system with adaptive moving target indicator, coherent signal processing, FFTs, and variable pulse repetition frequency. The entire PESA antenna array can swivel 360 degrees on a rotating platform. This allows the radar antenna to be rapidly repositioned, and even conduct all round surveillance.<ref>[http://www.bharat-rakshak.com/MISSILES/Images/Rajendra.jpg Rajendra Radar, image copyright Bharat Rakshak and DRDO] {{webarchive |url=https://web.archive.org/web/20090226074048/http://www.bharat-rakshak.com/MISSILES/Images/Rajendra.jpg |date=26 February 2009 }}</ref>

*[[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 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 modernization program, and two of another variant were ordered by the Indian Navy for their 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 |date= |accessdate=2010-08-31}}</ref><ref>{{cite web|url=http://economictimes.indiatimes.com/PoliticsNation/IAF_going_through_stage_of_modernisation_Major/articleshow/3705906.cms |title=IAF modernisation |publisher=Economictimes.indiatimes.com |date=2008-11-12 |accessdate=2010-08-31}}</ref>
