Principle. When a traditional RACON receives a radar pulse, it responds with a signal which on a radar screen takes the form of a short line of dashes and dots forming a Morse character radiating away from the location of the beacon. Typically, the Morse character starts with a dash – a long, continuous signal.
In track-while-scan mode the radar has the ability to acquire and lock/track multiple targets while simultaneously providing a view of the surrounding airspace, which in turn aids the pilot and or operator in maintaining better situational awareness. [1]
Rayon, also called viscose [1] and commercialised in some countries as sabra silk or cactus silk, [2] is a semi-synthetic fiber, [3] made from natural sources of regenerated cellulose, such as wood and related agricultural products. [4] It has the same molecular structure as cellulose.
DEFCON. The defense readiness condition ( DEFCON) is an alert state used by the United States Armed Forces. [1] [2] For security reasons, the US military does not announce a DEFCON level to the public. [1] The DEFCON system was developed by the Joint Chiefs of Staff (JCS) and unified and specified combatant commands. [3]
The nuance and history of the Israeli-Palestinian conflict remains difficult to capture succinctly, particularly during escalating turmoil among groups with deep-held—and entrenched—views on ...
For example, when one is navigating through a dense forest they are using spatial perception and awareness. Another example is when trying to understand the relations and mechanics inside of a car, they are relying on their spatial perception to understand its visual framework.
The KLJ-7, also referred to as the Type 1478, is an X band airborne fire-control radar (FCR) developed by Nanjing Research Institute of Electronic Technology (NRIET), also known as the China Electronics Technology Company's (CETC's) No. 14 Research Institute.
In aviation, a terrain awareness and warning system (TAWS) is generally an on-board system aimed at preventing unintentional impacts with the ground, termed "controlled flight into terrain" accidents, or CFIT.
In statistics, the mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x =argmax x i P( X = x i ) ).
The High-frequency Active Auroral Research Program ( HAARP) is a University of Alaska Fairbanks program which researches the ionosphere – the highest, ionized part of Earth's atmosphere . The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power radio frequency transmitter facility operating in the high ...
