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.
