Passive radar — systems (also referred to as passive coherent location and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non cooperative sources of illumination in the environment, such as… … Wikipedia
Passive monitoring — is a technique used to capture traffic from a network by generating a copy of that traffic, often from a span port or mirror port or via a network tap. Once the data (a stream of frames or packets) has been extracted, it can be used in many… … Wikipedia
Passive infrared sensor — A Passive InfraRed sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR based motion detectors (see below). Apparent… … Wikipedia
Kolchuga passive sensor — The Kolchuga passive sensor is an ESM system developed in Ukraine. Its detection range is limited by line of sight but may be up to 800 km (500 miles) for very high altitude, very powerful emitters. Frequently referred to as Kolchuga Radar , the… … Wikipedia
VERA passive sensor — VERA VERA passive radiolocator (in Czech known as Věra ) is an electronic support measures (ESM) system that uses measurements of time difference of arrival (TDOA) of pulses at three or four sites to accurately detect and track airborne emitters … Wikipedia
Kopáč passive sensor — Kopáč (the word means the digger in Czech) was an early electronic warfare support measures (ESM) system developed in Czechoslovakia in the early 1960 s that used measurements of time difference of arrival (TDOA) of pulses at three sites to… … Wikipedia
Ramona passive sensor — Ramona was the second generation Czechoslovakian electronic support measures (ESM) system that uses measurements of time difference of arrival (TDOA) of pulses at three or four sites to accurately detect and track airborne emitters by… … Wikipedia
Tamara passive sensor — Tamara was the third generation Czechoslovak electronic support measures (ESM) system that used measurements of time difference of arrival (TDOA) of pulses at three or four sites to accurately detect and track airborne emitters by multilateration … Wikipedia
Monitoring and Measurement in the Next Generation Technologies — (MOMENT) is a project aimed at integrating different platforms for network monitoring and measurement to develop a common and open pan European infrastructure. The system will include both passive and active monitoring and measurement techniques… … Wikipedia
Electro-optical MASINT — is a subdiscipline of Measurement and Signature Intelligence, (MASINT) and refers to intelligence gathering activities which bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT), Imagery… … Wikipedia
Ranging — is a process or method to determine the distance from one position to another position.Ranging is the term merely applying for distance metering with moving objects. Commonly used term for residing terrestrial objects is surveying.Classical… … Wikipedia
