WHAT IS ELECTRONIC WARFARE?
WHEN WE NEED ELECTRONIC WARFARE?
WHY WE NEED ELECTRONIC WARFARE?
IDEOLOGY BEHIND?
Electronic Warfare is a military action involving the use of
electromagnetic energy to determine, exploit, reduce, or
prevent the hostile use of electromagnetic spectrum as well as
action which retains friendly use of electromagnetic spectrum.
The Spectrum uses wide range of waves,
The electromagnetic spectrum covers electromagnetic waves
with frequencies ranging from below one hertz to above
1025 hertz.
When we need Electronic Warfare
The Spectrum range provide us:
Electronic Support Measures.
Electronic Counter Measures.
Basic Idea….
.
Electronic Support Measure is that division of electronic
warfare which involves actions taken to search for,
intercept, locate, record and analyze radiated
electromagnetic energy, for the purpose of exploiting such
radiations to support military operations.
Thus, ESM is an important source of EW
information to carry out electronic countermeasures and
electronic, counter- countermeasures.
Electronic Counter measures are the actions taken to
prevent or reduce the enemy's effective use of the
electromagnetic spectrum. Two major actions of ECM
are jamming and deception.
Jamming.
The deliberate radiation, re-radiation, or reflection of electromagnetic
energy to impair the use of electronic devices, equipment or systems is
called Jamming.
Deception.
The deliberate radiation, re-radiation, alteration, absorption, or reflection of
electromagnetic energy in a manner intended to mislead the enemy in the
interpretation or use of information received by his electronic systems is called
deception.
There are two categories of deception.
Manipulative.
The alteration or simulation of friendly electromagnetic radiations to
accomplish deception.
Imitative.
Introducing radiation into enemy channels which imitates his own
emission.
ELECTRONIC WARFARE IS BEING USED FOR
THE PURPOSE SUCH AS LIKE:
1. Safe guarding the outskirts of the Nation.
2. Keep the Intelligence and the premises safe.
3. Early warning radar system.
4. Drones.
