A Joint Surveillance Target Attack Radar System (JSTARS). ISTAR stands for intelligence, surveillance, target acquisition, and reconnaissance.In its macroscopic sense, ISTAR is a practice that links several battlefield functions together to assist a combat force in employing its sensors and managing the information they gather.
The terms "surveillance" and "reconnaissance" have sometimes been used interchangeably. In the military context, a distinction can be drawn between surveillance, which monitors a changing situation in real time, and reconnaissance, which captures a static picture for analysis. [3]
Modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance in addition to general intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual observation and scouting of enemy movement.
Reconnaissance, surveillance, and target acquisition (RSTA) squadrons are a type of unit in the United States Army. These are cavalry squadrons (though in IBCTs they typically contain at least one dismounted infantry troop), [ 1 ] [ 2 ] and act at the squadron ( battalion ) level as a reconnaissance unit for their parent brigade combat teams .
Intelligence, surveillance and reconnaissance may refer to: Joint Functional Component Command for Intelligence, Intelligence, surveillance, target acquisition, ...
Since reconnaissance is a basic military skill, "special" reconnaissance refers to the means of operating in the desired area, and the nature of the mission. In US Army doctrine, [10] [11] there are five basic factors: Physical distances: The area of operations may be well beyond the forward line of troops, and require special skills to reach ...
However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image. Through-the-wall radars can be made with Ultra Wideband impulse radar, micro- Doppler radar , and synthetic aperture radar (SAR).
Area reconnaissance refers to the observation, and information obtained, about a specified location and the area around it; it may be terrain-oriented and/or force-oriented. Ideally, a reconnaissance platoon, or team, would use surveillance or vantage (static) points around the objective to observe, and the surrounding area.
