Geospatial Intelligence
In the United States, geospatial intelligence (GEOINT) is intelligence about the human activity on Earth derived from the exploitation and analysis of imagery, signals, or signatures with geospatial information. GEOINT describes, assesses, and visually depicts physical features and geographically referenced activities on the Earth. GEOINT, as defined in US Code, consists of imagery, imagery intelligence (IMINT) and geospatial information. GEOINT knowledge and related tradecraft is no longer confined to the U.S. government, or even the world's leading military powers. Additionally, countries such as India are holding GEOINT-specific conferences. While other countries may define geospatial intelligence somewhat differently than does the U.S., the use of GEOINT data and services is the same. Geospatial Intelligence can also be referred to as "Location Intelligence". Although GEOINT is inclusive, HYDROSPATIAL is preferably used to refer and to focus on the aquatic and coastal zones ...

Synthetic-aperture Radar
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR). The distance the SAR device travels over a target during the period when the target scene is illuminated creates the large ''synthetic'' antenna aperture (the ''size'' of the antenna). Typically, the larger the aperture, the higher the image resolution will be, regardless of whether the aperture is physical (a large antenna) or synthetic (a moving antenna) – this allows SAR to create high-resolution images with comparatively small physical antennas. For a fixed antenna size and orientation, objects which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIGINT
Signals intelligence (SIGINT) is the act and field of intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). As classified and sensitive information is usually encrypted, signals intelligence may necessarily involve cryptanalysis (to decipher the messages). Traffic analysis—the study of who is signaling to whom and in what quantity—is also used to integrate information, and it may complement cryptanalysis. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmissions. Since the Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IMINT
Imagery intelligence (IMINT), pronounced as either as ''Im-Int'' or ''I-Mint'', is an intelligence gathering discipline wherein imagery is analyzed (or "exploited") to identify information of intelligence value. Imagery used for defense intelligence purposes is generally collected via satellite imagery or aerial photography. As an intelligence gathering discipline, IMINT production depends heavily upon a robust intelligence collection management system. IMINT is complemented by non-imaging MASINT electro-optical and radar sensors. History Origins Although aerial photography was first used extensively in the First World War, it was only in the Second World War that specialized imagery intelligence operations were initiated. High quality images were made possible with a series of innovations in the decade leading up to the war. In 1928, the RAF developed an electric heating system for the aerial camera. This allowed reconnaissance aircraft to take pictures from very high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DIKW Pyramid
The DIKW pyramid, also known variously as the knowledge pyramid, knowledge hierarchy, information hierarchy, DIKW hierarchy, wisdom hierarchy, data pyramid, and information pyramid, sometimes also stylized as a chain, refer to models of possible structural and Function model, functional relationships between a set of components—often four, data, information, knowledge, and wisdom—models that had antecedents prior to the 1980s. In the latter years of that decade, interest in the models grew after explicit presentations and discussions, including from Milan Zeleny, Russell Ackoff, and Robert W. Lucky. Subsequent important discussions extended along theoretical and practical lines into the coming decades. While debate continues as to actual meaning of the component terms of DIKW-type models, and the actual nature of their relationships—including occasional doubt being cast over any simple, linear, unidirectional model—even so they have become very popular visual representa ...

Denial And Deception
Denial and deception (D&D) is a Western theoretical framework for conceiving and analyzing military intelligence techniques pertaining to secrecy and deception. Originating in the 1980s, it is roughly based on the more pragmatic Soviet practices of '' maskirovka'' (which preceded the D&D conceptualization by decades) but it has a more theoretical approach compared to the latter.Hutchinson, William. (2004) "The Influence of Maskirovka on Contemporary Western Deception Theory and Practice." Proceedings of the 3rd European Conference on Information Warfare and Security. . Description In the D&D framework, denial and deception are seen as distinct but complementary endeavors. Denial most often involves security and concealment to prevent foreign agents, photographic surveillance, electronic monitoring, or even the media from revealing secretive diplomatic or military matters. Deception is the construction of a false reality for the adversary through intentionally " leaked" false inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Intelligence (intelligence Gathering)
Human intelligence (HUMINT, pronounced ) is List of intelligence gathering disciplines, intelligence-gathering by means of human sources and interpersonal communication. It is distinct from more technical intelligence-gathering disciplines, such as signals intelligence (SIGINT), imagery intelligence (IMINT), and measurement and signature intelligence (MASINT). HUMINT can be conducted in a variety of ways, including via espionage, reconnaissance, interrogation, witness interviews, or torture. Although associated with military and intelligence agencies, HUMINT can also apply in various civilian sectors such as law enforcement. Overview NATO defines HUMINT as "a category of intelligence derived from information collected and provided by human sources." A typical HUMINT activity consists of interrogations and conversations with persons having access to information. As the name suggests, human intelligence is mostly collected by people and is commonly provided via espionage or some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
