The AN/SLR-25 is a passive cryptologic exploitation system principally for tactical use, but that can make contributions to higher levels of intelligence. The SLR-25(V)1 Advanced Cryptologic Carry-on Exploitation System (ACCES) is a portable version of the SLR-25(V)2 SSEE (Ship Signal Exploitation Equipment) without dedicated SIGINT spaces.

[10] Russia and China, at various times, have operated or are operating intercept stations in Cuba, as well as Cuban-operated facilities.
Even measurement and signature intelligence (MASINT) preceded electronic intelligence (ELINT), with sound ranging techniques for artillery location. SIGINT is the analysis of intentional signals for both communications and non-communications (e.g., radar) systems, while MASINT is the analysis of unintentional information, including, but not ...
Signal collectors, which concentrate the energy, as with a telescope lens, or a radar antenna that focuses the energy at a detector; Signal detectors, such as charge-coupled devices for light or a radar receiver; Signal processing, which may remove artifacts from single images, or compute a synthetic image from multiple views; Recording mechanism
“Together with our interagency partners, the FBI issued guidance to enhance the visibility of network defenders and to harden devices against People’s Republic of China-affiliated exploitation.”
Communications intelligence (COMINT) Electronic intelligence (ELINT) – gathered from electronic signals that do not contain speech or text (which are considered COMINT) Foreign instrumentation signals intelligence (FISINT) – entails the collection and analysis of telemetry data from a missile or sometimes from aircraft tests; formerly known ...
