Option 3 : Advanced Chaff Technology

The correct answer is Advanced Chaff Technology.

  • Advanced Chaff Technology was developed by Defence Research and Development Organisation to protect naval ships against missile attacks in April 2021.
  • To protect naval ships from enemy missile attacks, the Defense Research and Development Organization (DRDO) has created an Advanced Chaff Technology.
  • It is an additional step in the direction of Atmanirbhar Bharat.
  • Chaff is an electronic countermeasure device that is employed by militaries all over the world to shield naval ships or other sensitive targets from the radar and radio frequency (RF) guiding mechanisms of the adversary missile.
  • The deployed chaff rockets in the air serve as various targets for missile guidance systems and deflect enemy missiles, thereby defending their own assets.
  • Short Range Chaff Rocket (SRCR), Medium Range Chaff Rocket (MRCR), and Long Range Chaff Rocket are the three indigenous versions of the crucial technology that DRDO has developed (LRCR).

  • The temperature of an object is measured using infrared (IR) imaging technology. All objects give off electromagnetic radiation, mostly in the infrared (IR) range, which is invisible to the unaided eye.
  • Lightweight surveillance radar that can be operated by one person only is known as man-portable radar.
  • Covered shooting ranges called baffle firing ranges guard against mishaps caused by stray bullet wounds.
