All Mobile Radar Systems Developed by DRDO

4 min read

Radar is basically a highly efficient system that is used to detect the direction, presence, distance, velocity of ships & aircrafts and other objects by emitting radio waves. A radar system has a transmitter that pulses off electromagnetic waves that corresponds to the microwave or radio wave section of the spectrum. Radio waves that are emitted from the transmitter will reflect off the object and return to the receiver, providing detailed information regarding speed and location of the object. The Defence forces of India are using this technology to detect their aircrafts, ships and land-based vehicles. This has enhanced the combating capabilities of the Indian Armed forces and helped them keep an upper hand over their nemesis. 


The Indian Defence forces have upgraded themselves by adopting mobile radar systems. These systems can be deployed to anywhere in less time. Mobile radar systems have a long life and can easily expand the surveillance range. The combating capabilities of the defence forces have induced youngsters to join these forces and serve their nation. They can fulfil their dream of joining the defence forces of India by clearing exams like AFCAT, NDA,CDS etc. Those who have intense passion to qualify NDA exam, they can connect with a reputed institute that caters perfect NDA coaching in Chandigarh. Before joining the defence forces of India, aspiring candidates should have clear ideas about the mobile radar systems used by them while deterring various attacks.


List of mobile radar systems developed by DRDO(Defence Research and Development Organization) are mentioned hereunder:


  1. Swathi Weapon locating radar


It is an array radar that is electronically scanned and active phased. This radar is capable of locating antagonistic mortars, artillery and rocket launchers and can track friendly fire to locate the affected points. Swati is designed specially to detect the objects with a small cross-section across the battlespace area. It is efficient in tracking the fire based weapons that are positioned at different locations. Swati radar has features like rapid deployment, high mobility and decamp. In addition to this, it consists of antenna, radar shelter and cooling mechanisms that are located on mobile platforms. Its entire system is modelled to overcome physical rigors of the battlefield. 

  • Rajendra Radar


It is a multifunction array radar system that is electronically scanned. For the air defence weapon system, it acts as a primary sensor. It can expand its range upto 90 kms. It can easily track multiple objects and incoming missiles. Rajendra radar offers guidance for commanding missiles. It has waveform readiness. It can easily manage 4 targets along with 8 missiles. Rajendra Radar has an efficient technique of tracking 64 targets side by side. It is capable of operating in cued acquisitions and in a variety of search modes. Rajendra radar can be easily operated from the control centre. 


Are you planning to be a part of the Indian Air force? If yes, prepare well for the AFCAT exam. In case you need perfect mentoring for the exam, then approach a brilliant institute that offers excellent AFCAT coaching in Chandigarh.

  • INDRA Radar


INDRA ( Indian Doppler Radar), also named as “Low Flying Detection Radar”. It consists of a series of 2D radars developed by LRDE i.e. lab of Defence Research and Development Organization. INDRA radar is produced by Bharat Electronics. The INDRA-1 is a mobile surveillance radar system to detect low level targets. The INDRA-2 is efficient in intercepting ground level targets. These radars can easily target air-based objects. They work on L band frequency. It can easily expand its range upto 90 kms and track 200 objects at a time. The INDRA radars were exported to Srilanka as well. 

  • Ashwini Radar


This radar is used by the Indian Airforce that is low-level transportable radar. Ashwini radar has 4D active array technology that can accurately target highly maneuverable objects. It provides information related to the velocity vector of the incoming target along with its range, height and azimuth. Ashwini radar provides awareness against high-speed aircraft that range upto 200 kms. The Indian Airforce of India has planned to purchase 18 such radars. These radars started to provide its services in 2018. 

If anyone needs proper conditioning while studying for the exam, they can join the most esteemable institute that provides first-class CDS coaching in Chandigarh. 

  • The Rohini Radar


The Rohini is a medium range 3D multifunction radar. It is an air surveillance radar that is mounted on the BEML tatra truck and supported by a mobile auxiliary power unit. This radar system has been developed by the LRDE lab of Defence Research and Development Organization(DRDO). Astra Microwave and Larsen & toubro are two leading companies that provided their assistance in development of the Rohini radar system. 


Rohini radar can easily detect and track multiple objects flying simultaneously and ascertain their position. It can expand its horizontal range upto 170 kms. The Rohini Radar system can easily track low altitude targets. 


There are many youngsters who have a deep desire to become an officer in the Indian Air Force. They can start preparing for the AFCAT exam. If anyone needs sterling guidance, they can find an illuminating institute that delivers superb AFCAT coaching in Chandigarh.




The mobile radar systems developed by DRDO are listed above. From here, you can easily deduce that the defence forces of India have upgraded themselves technically which has helped them in combating noxious attacks and safeguarding the peace of their motherland.
