The Advent of Radar Age in India

Imagine you're thrust with the responsibility of landing a big jet on to the landing zone. All that you see is dense and thick fog beneath you and there is no way that your human eyes can possibly figure out where the strip of land is located. This foreseen difficulty during foggy nights is overcome with the help of radar, which makes use of high-frequency radio waves to 'see' where you're supposed to land.

Radar makes use of an electromagnetic sensor to detect, locate and track objects by making use of radio waves. It was developed initially to track enemy aircrafts during World War II. It works by emanating electromagnetic energy towards the object and the echo received from the target is observed. The objects or targets can be ships, aircraft, vehicles, astronomical bodies or sometimes even birds and insects.

Apart from locating the presence as well as the velocity of these objects, radar also helps in determining the size and shape as well. What makes radar a class apart from other detecting devices is its potential to detect faraway objects in any kind of weather condition without affecting its precision.

Did you know that Electronics and Radar Development Establishment (LRDE) caters to the development of radar in India? This laboratory comes under the Defense Research and Development Organization (DRDO). LRDE has successfully developed several radar systems and has installed them in the Indian Armed Forces.

The success stories of LRDE in the deployment of radar technology in the armed forces is a clear indication that its growth has been positive in India. It clears the path of DRDO to make India fiercely independent in terms of military technology and henceforth decreases the importing of foreign military equipment.

The initial projects of DRDO only consisted of short-range 2D systems. Currently, it manufactures high power 3D systems, fire control radars as well as airborne surveillance. Along with these, DRDO also has many other radar systems that are being developed.


Here are the top three examples of successful radar implementations in India

aerospace engineering design   Active Electronically Scanned Array (AESA) radar is the best example of the success story of radar technology in India. Defense Research and Development Organization (DRDO), the pioneer behind AESA had displayed this masterpiece at Aero India show that had happened this year in Bangalore. It was installed on Tejas, the fighter aircraft and about a hundred of these systems have been ordered already by the Indian Air Force.
aerospace engineering design   As per the recent reports in 2019, the latest radar equipment offers better ship survivability due to improved performance. The state-of-the-art facility of this new technology helps in electronically steering the radar beam. This negates the effort needed to mechanically rotate the antenna atop the mast of the ship. This improved technology replaces the rotating antenna in the ship's mast with a fixed antenna, thus reducing problems like radar cross-section. Further, the new technology is cost effective and also improves the prolonged sustenance of the ship. By the end of 2019, this technology will be available to everyone.
aerospace engineering design   LRDE has partnered with several governments as well as private companies for the production of radars for the Indian Armed Forces. Some of these radars are INDRA (Indian Doppler Radar), RAJENDRA Radar, Central Acquisition Radar (3D-CAR), Swathi Weapon Locating Radar (WLR), Ashwini Radar, Arudhra Radar, and PJT-531 Battle Field Surveillance Radar. These radars have been a boon to the Indian Armed Forces and helped in countering terrorism and infiltration especially in LOC and other borders. Further, it helped in locating the Pakistani artillery positions with the capacity of tracking seven targets at the same time.
