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]
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 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.
Awareness is a relative concept. It may be focused on an internal state, such as a visceral feeling, or on external events by way of sensory perception. [3] It is analogous to sensing something, a process distinguished from observing and perceiving (which involves a basic process of acquainting with the items we perceive). [4]
Situational awareness or situation awareness (SA) is the understanding of an environment, its elements, and how it changes with respect to time or other factors. Situational awareness is important for effective decision making in many environments.
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 ...
