Recently, the Defence Research and Development Organisation (DRDO) handed over the Medium Range-Microwave Obscurant Chaff Rocket (MR-MOCR) to the Indian Navy at a ceremony held in New Delhi.

About Microwave Obscurant Chaff Rocket: 

  • Microwave Obscurant Chaff (MOC) is a niche technology developed by DRDO’s Defence Laboratory, Jodhpur, 
  • It obscures radar signals and creates a microwave shield around platforms and assets, thus reducing radar detection.
  • Special type of fibres, with diameter of a few micrometers and unique microwave obscuration properties, has been assembled in the medium range chaff rocket.
  • How does it function?: When the rocket is fired it forms a microwave obscurant cloud in space spreading over a sufficient area, with adequate persistence time, thus creating an effective shield against hostile threats having Radio Frequency seekers.
  • DRDO has indigenously developed three variants of this critical technology namely Short Range Chaff Rocket (SRCR), Medium Range Chaff Rocket (MRCR) and Long Range Chaff Rocket (LRCR).
  • Phases
    • The Phase-I trials of MR-MOCR were successfully conducted from Indian Navy ships, demonstrating the MOC cloud blooming and being persistent in space.
    • In Phase-II trials, the Radar Cross Section (RCS) reduction of an aerial target to the extent of 90 per cent has been demonstrated and cleared by the Indian Navy.

Q1: What is Radiation?

It is energy that moves from one place to another in a form that can be described as waves or particles.
