How will DRDO’s Chaff technology protect Indian warships and fighter jets?


In the field of defence, India is taking another step towards becoming “atmanirbhar”. Indian Air Force [IAF] and the Indian Navy have partnered with the Defense Research and Development Organization [DRDO] develop the CHAFF system, which will protect warships and aircraft from missile attacks. After the United States, India is the only country to develop this technology.

As India focuses on improving its defense capabilities, this finding is significant. China has increased its funding and now has anti-ship ballistic missiles like the DF-21 in its arsenal. At times like these, India needs CHAFF technology to protect its warships and aircraft against hostile radar threats.

CHAFF is an important defense system that protects fighter jets and naval vessels from hostile radar threats.

The importance of this technology stems from the fact that a small amount of chaff deployed in the air functions as a decoy, deflecting hostile missiles and providing security for fighter jets and warships. According to The Hindustan Times, CHAFF creates a cloud of metal particles around the jet or ship which deflects the missiles.

“In today’s electronic warfare, the survivability of fighter aircraft is of paramount importance due to advances in current radar threats,” the Department of Defense said during CHAFF’s induction, adding that the technology was needed to protect fighter jets.

What is the content of the straw?

Sequins are made of thin rods of metallized glass or plastic, along with thin metal sheets or wires, and are designed to replicate the wavelength of enemy radar frequency. According to the DRDO, they are used in the form of cartridges “filled with large quantities of glitter of various sizes”.

What is the mechanism of technology?

CHAFF is part of a countermeasure delivery system [CMDS], which uses passive jamming to counter threats such as infrared and radar. CHAFF is designed to resist radar weapons, while flares are designed to guard against incoming heat-seeking missiles by generating a diversion with a larger heat signature that pushes the missile away.

Chaff and flares are “passive” consumable countermeasures [ECMs] which aim to deceive hostile systems by “employing confusion reflectors” by chemical or mechanical means, according to the DRDO. ECMs that are “active” operate by “transmitting electromagnetic energy”. “like fake jamming or noise jamming

According to the DRDO, Chaff is an “electronic analog of smoke” that uses electromagnetic waves to “confuse or deceive an enemy system.” “..”When injected into the wake of the aircraft, the chaff packets open up…to generate a radar-reflecting cloud called a chaff corridor,” according to the nonprofit Federation of American Scientists. lucrative research and policy advocacy.The dropping of chaff “confuses the radars so much that they are unable to locate the real targets in the cloud of chaff”, according to the Pentagon.

According to the DRDO, glitter “appears[s] on the adversary’s radar screens, either as a smudge obscuring the true target, or as hundreds of false targets surrounding the true target.

Short Range Sequin Rocket [SRCR]Medium Range Sequin Rocket [MRCR]and long range sequin rocket [LRCR] are three varieties of this vital technology developed by Defense Laboratory Jodhpur [DLJ]a DRDO laboratory (LRCR).

He worked on the project with the Pune-based High Energy Materials Research Laboratory [HEMRL].

The DRDO has also developed an improved CHAFF-118/I cartridge for the Indian Air Force, which has significant improvements over existing CHAFF technology in terms of effectiveness against higher frequency radar threats in modern fights. The IAF deemed the performance of the native-118/I chaff cartridge sufficient after rigorous user trials and began the process of integration into the Indian Air Force, according to HT.

Last April, the CHAFF system was created to protect Indian Navy ships from missile attacks.
