Electronic Warfare — Prelims Strategy

Prelims Strategy

For Prelims, the strategy for Electronic Warfare (EW) should focus on factual recall and conceptual clarity. Begin by thoroughly understanding the core definitions: Electronic Warfare itself, and its three pillars – Electronic Attack (EA), Electronic Protection (EP), and Electronic Warfare Support (ES).

Be able to distinguish clearly between these three, as this is a common trap. Memorize key technical terms like jamming, deception, SIGINT (COMINT/ELINT), ECCM, frequency hopping, and spread spectrum.

Pay close attention to India's indigenous EW systems, specifically Samyukta (Indian Army) and Sangraha (Indian Navy), along with the role of DRDO defense research and electronic warfare in their development.

Understand the basic applications of EW across different military domains (land, air, sea, space). Current affairs related to new EW system inductions, upgrades, or their use in recent global conflicts are also high-priority.

Focus on the 'what' and 'how' of EW, identifying specific technologies and their functions. Practice MCQs that test definitions, examples, and the correct association of systems with their respective services or functions.

A strong grasp of these fundamentals will ensure success in Prelims questions on this topic.
