Electromagnetic Warfare and Protection Techniques

This set of flashcards covers key terms and concepts related to Electromagnetic Warfare and Protection Techniques.

Electromagnetic Spectrum (EMS)

The range of frequencies of electromagnetic radiation from zero to infinity.

Electromagnetic Warfare (EW)

Military action involving the use of electromagnetic energy to determine and exploit the electromagnetic spectrum.

Electromagnetic Attack (EA)

The deliberate radiation, reradiation, or reflection of electromagnetic energy to prevent or reduce an enemy's use of the electromagnetic spectrum.

Jamming

The deliberate transmission of radio frequency signals to disrupt communications by blocking or interfering with the transmission.

Electromagnetic Support (ES)

The use of direction-finding techniques to locate threat transmitters and direct actions accordingly.

Electromagnetic Protection (EP)

Actions taken to protect personnel, facilities, and equipment from electromagnetic interference.

Emissions Control (EMCON)

Tactics to control the emission of electromagnetic energy to avoid detection and protection from enemy actions.

Signal to Noise Ratio (SNR)

The ratio of the strength of a desired signal to the background noise at the receiver's location.

Direction Finding (DF)

Techniques used to determine the direction from which a signal is transmitted.

Brigade Combat Team (BCT)

A combined arms unit in the Army consisting of infantry, armor, and supporting units.

Tactical Radio Operations

Procedures and techniques used to conduct radio communications in military operations.

Counter-SUAS

Measures to counter Unmanned Aerial Systems (drones) through various means including jamming.

CEMA

Cyber Electromagnetic Activities, integrating cyber operations with electromagnetic spectrum operations.

Signal-to-Jamming Ratio (SJR)

The measure of the desired signal's strength compared to the jamming signal's strength.

Triangulation

A method in DF using multiple sensors to locate a transmitter's position by intersecting lines of bearing.

Radio Frequency (RF) Noise

Unwanted electromagnetic signals that interfere with the reception of desired signals.

PERSISTENT WIRELESS TRACKING

Continuous monitoring and processing of radio frequency signals to maintain data on targets.

Limited Operations

Controlled use of equipment to minimize exposure or detection by adversaries.
