About Electronic Warfare (EW)

Definition: A military action involving the use of electromagnetic energy to determine, exploit, reduce, or prevent the hostile use of electromagnetic spectrum signals (such as radio, infrared, or radar).
Three Major Areas:
- Electronic Support Measures (ESM or passive EW): Intercepts and analyzes electromagnetic signals for threat recognition, intelligence gathering, and operational planning.
- Electronic Counter- Measures (ECM or active EW): Defends against jamming and deception using cyber and multispectral tools, and protecting friendly forces' communications.
- Electronic Counter- Countermeasures (ECCM): Employs electromagnetic signals or directed energy to disrupt and neutralize enemy electromagnetic capabilities.
Challenges faced by EW System: Rapid technological changes require continuous updates in EW capabilities; cyber-attacks etc.

Need EW for India

To strengthens national defense by countering advanced threats in the electromagnetic spectrum from enemy countries.
- E.g., China’s Y-9LG electronic warfare platform.
EW Systems in India
- Shakti EW system: Provide an electronic layer of defence against modern radars and anti-ship missiles.
- Programme Sangraha: Joint DRDO-Navy Programme for design and development of five different types of indigenous EW systems.
- Integrated Electronic Warfare System (IEWS): Designed for plains, semi-desert regions and mountainous terrain.
- Other: Himshakti ((IEWS), Samyukta (designed to perform multiple jamming), etc.
