Back 22

technical and geolocation intelligence derived from foreign
noncommunications electromagnetic radiations emanating from other than nuclear detonations or
radioactive sources (JP 1-02).

Front 23

Electronics security is

Back 23

the protection resulting from all measures designed to deny unauthorized
persons information of value that might be derived from their interception and study of
noncommunications electromagnetic radiations, e.g., radar (JP 1-02).

electromagnetic energy (JP 1-02).

Front 25

Electromagnetic interference is

Back 25

any electromagnetic disturbance that interrupts, obstructs, or
otherwise degrades or limits the effective performance of electronics and electrical equipment. It can be
induced intentionally, as in some forms of electronic warfare, or unintentionally, as a result of spurious emissions and responses, intermodulation products and the like (JP 1-02)

Front 26

Electronic masking is

Back 26

the controlled radiation of electromagnetic energy on friendly frequencies in a
manner to protect the emissions of friendly communications and electronic systems against enemy
