Q

Define “Electronic Warfare Reprogramming.”

A

Electronic warfare reprogramming is the deliberate alteration or modification of electronic warfare
or target sensing systems, or the tactics and procedures that employ them, in response to validated changes in equipment, tactics, or the electromagnetic environment. These changes may be the result of deliberate actions on the part of friendly, adversary, or third parties; or may be brought about by electromagnetic interference or other inadvertent phenomena. The purpose of electronic warfare reprogramming is to maintain or enhance the effectiveness of electronic warfare and target sensing system equipment.
Electronic warfare reprogramming includes changes to self-defense systems, offensive weapons systems, and intelligence collection systems (JP 3-13.1).

44
Q

b. mutual interference among friendly systems; and/or c. enemy interference with the ability to execute a military deception plan (JP 1-02).

45
Q

Define “Electromagnetic Spectrum Management.”

A

Electromagnetic spectrum management is planning, coordinating, and managing joint use of the electromagnetic spectrum through operational, engineering, and administrative procedures. The objective of spectrum management is to enable electronic systems to perform their functions in the intended environment without causing or suffering unacceptable interference (JP 6-0).

46
Q

Define “Wartime Reserve Modes.”

A

Wartime reserve modes are characteristics and operating procedures of sensors, communications,
navigation aids, threat recognition, weapons, and countermeasures systems that will contribute to military effectiveness if unknown to or misunderstood by opposing commanders before they are used, but could be exploited or neutralized if known in advance. Wartime reserve modes are deliberately held in reserve for wartime or emergency use and seldom, if ever, applied or intercepted prior to such use (JP 1-02).

47
Q

Define “Electromagnetic Compatibility.”

A

Electromagnetic compatibility is the ability of systems, equipment, and devices that utilize the
electromagnetic spectrum to operate in their intended operational environments without suffering
unacceptable degradation or causing unintentional degradation because of electromagnetic radiation or
response. It involves the application of sound electromagnetic spectrum management; system, equipment, and device design configuration that ensures interference-free operation; and clear concepts and doctrines that maximize operational effectiveness (JP 1-02).

48
Q

Define “Control” in respect to EW.

A

In the context of EW, control of the electromagnetic spectrum is achieved by effectively coordinating friendly systems while countering enemy systems. Electronic attack limits enemy use of the electromagnetic spectrum. Electronic protection secures use of the electromagnetic spectrum for friendly forces, and electronic warfare support enables the commander’s accurate assessment of the situation.
All three are integrated for effectiveness. Commanders ensure maximum integration of communications; intelligence, surveillance, and reconnaissance; and information tasks.

49
Q

Define “Detection.”

A

In the context of EW, detection is the active and passive monitoring of the operational environment
for radio frequency, electro-optic, laser, infrared, and ultraviolet electromagnetic threats. Detection is the first step in EW for exploitation, targeting, and defensive planning. Friendly forces maintain the capability to detect and characterize interference as hostile jamming or unintentional electromagnetic interference.

50
Q

Define “Denial.”

A

In the context of EW, denial is controlling the information an enemy receives via the electromagnetic spectrum and preventing the acquisition of accurate information about friendly forces. Degradation uses traditional jamming techniques, expendable countermeasures, destructive measures, or network applications. These range from limited effects up to complete denial of usage.

51
Q

Define “Deception.”

A

In the context of EW, deception is confusing or misleading an enemy by using some combination of
human-produced, mechanical, or electronic means.
Through use of the electromagnetic spectrum, EW deception manipulates the enemy’s decision loop, making it difficult to establish accurate situational
awareness.

52
Q

Define “Disruption and Degradation.”

A

In the context of EW, disruption and degradation techniques interfere with the enemy’s use of the
electromagnetic spectrum to limit enemy combat capabilities. This is achieved with electronic jamming, electronic deception, and electronic intrusion. These enhance attacks on hostile forces and act as force multipliers by increasing enemy uncertainty, while reducing uncertainty for friendly forces. Advanced electronic attack techniques offer the opportunity to nondestructively disrupt or degrade enemy infrastructure.

53
Q

Define “Protection.”

A

In the context of EW, protection is the use of physical properties; operational tactics, techniques, and procedures; and planning and employment processes to ensure friendly use of the electromagnetic spectrum. This includes ensuring that offensive EW activities do not electronically destroy or degrade friendly intelligence sensors or communications systems. Protection is achieved by component hardening, emission control, and frequency management and deconfliction. Frequency management and deconfliction
include the capability to detect, characterize, geolocate, and mitigate electromagnetic interference that affects operations. Protection includes other means to counterattack and defeat enemy attempts to control the electromagnetic spectrum. Additionally, organizations such as a joint force commander’s EW staff or a joint EW coordination cell enhance electronic protection by deconflicting EW efforts.

54
Q

Define “Destruction.”

A

Destruction, in the context of EW, is the elimination of targeted enemy systems. Sensors and
command and control nodes are lucrative targets because their destruction strongly influences the enemy’s perceptions and ability to coordinate actions. Various weapons and techniques ranging from conventional munitions and directed energy weapons to network attacks can destroy enemy systems that use the electromagnetic spectrum. Electronic warfare support provides target location and related information.
While destroying enemy equipment can effectively deny the enemy use of the electromagnetic spectrum, the duration of denial will depend on the enemy’s ability to reconstitute. (See JP 3-13.1.)
