Intelligence without communications is irrelevant
Communications without intelligence is noise

Electronic Warfare• Why
• What
• Mostly Definitions and Concepts
Winter 2004 4
Why study EW?• Subset of IO
Actions taken to affect adversary information and information systems while defending one's own information and information systems
note - media ops not part of info ops in Canada
Winter 2004 5
Information Warfare• Any action taken to deny, exploit,
corrupt or destroy the enemy’s information and its functions; protecting ourselves against those actions; and exploiting our own military information functions
Winter 2004 6
What is EW?• The direct application of IO
• EM spectrum is becoming an integral part of warfare
If you can’t communicate, you’re dead
Winter 2004 7
Electronic Warfare• Military action taken to exploit the
EM spectrum which encompasses the interception and identification of EM emissions, the employment of EM energy to reduce or prevent hostile use of the EM spectrum, and actions taken to ensure its effective use by friendly forces.
Winter 2004 8
Technical Stuff• Spectrum classification communications vs EW
600 MHz = UHF = L band = C band
• Transmissivity
Winter 2004 9
newer goal is to reduce opponent’s SA
Traditional EW• Goal is spectrum superiority• direction finding (DF) will find • jamming will strike• intercept will provide information• false nets will deceive• integrate EW into all ops, deep, close
and rear.

ECM Electronic Countermeasures
• Also known as EA - Electronic Attack
That division of EW involving actions taken to prevent or reduce and enemy’s effective use of the EM spectrum, through the use of EM energy
Examples
JammingDeceptionNeutralization

EPM Electronic Protective Measures
• Also known as EP - Electronic Protection
That division of EW involving actions taken to ensure friendly effective use of the EM spectrum, despite the enemy’s use of EM energy
Examples

ESM Electronic Support Measures
• Also known as ES - Electronic Support That division of EW involving actions taken to
search for, intercept and identify EM emissions, and locate their sources for the purpose of immediate threat recognition

ER Electronic Reconnaissance
• Part of ESM ER involves the detection, identification,
evaluation and location of foreign EM radiations emanating from other than nuclear detonation or radioactive sources
Same as ESM?
Winter 2004 15
ER & ESM• Gather knowledge of the enemy’s
use of the EM spectrum
• ER is usually strategic• ESM is usually tactical

Role of EW Organizations• provide immediate threat wng• to provide tac SIGINT in sp of current ops and
future planning• provide target locations• provide ECM (now also called Electronic Attack
– EA) support to unit or fmn ops• provide advice to decrease friendly
vulnerabilities (ECCM or Electronic Protection - EP)

Divisions of EW• Military action taken to exploit the
EM spectrum which encompasses the interception and identification of EM emissions, the employment of EM energy to reduce or prevent hostile use of the EM spectrum, and actions taken to ensure its effective use by friendly forces.

Review• Why do we study EW?
• What is the difference between Army and Air Force EW?
• What are the three purposes of EW?
