Radar beacon (short: racon) is – according to article 1.103 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1] – defined as "A transmitter-receiver associated with a fixed navigational mark which, when triggered by a radar, automatically returns a distinctive signal which can appear on the display of the ...
Mode S transponders are compatible with Mode A and Mode C Secondary Surveillance Radar (SSR) systems. [2] This is the type of transponder that is used for TCAS or ACAS II ( Airborne Collision Avoidance System ) functions, and is required to implement the extended squitter broadcast, one means of participating in ADS-B systems.
An ATC ground station consists of two radar systems and their associated support components. The most prominent component is the PSR. It is also referred to as skin paint radar because it shows not synthetic or alpha-numeric target symbols, but bright (or colored) blips or areas on the radar screen produced by the RF energy reflections from the target's "skin."
SHORAN is an acronym for SHOrt RAnge Navigation, a type of electronic navigation and bombing system using a precision radar beacon. It was developed during World War II and the first stations were set up in Europe as the war was ending, and was operational with Martin B-26 Marauders based in Corsica, and later based in Dijon and in B-26s given ...
The civil transponder interrogation modes A and C were defined in air traffic control (ATC) and secondary surveillance radar (SSR) in 1960. The code is named after Ronald Lionel Gillham, a signals officer at Air Navigational Services, Ministry of Transport and Civil Aviation , who had been appointed a civil member of the Most Excellent Order of ...
A ramark, syllabic acronym for radar marker, was a type of radar beacon used to mark maritime navigational hazards. Ramarks are no longer in use. Ramarks are a non-directional, continuously transmitting radar beacon which indicate the bearing to a navigational hazard when viewed on a radar plan position indicator (PPI) display. [1]
A blind approach beacon system or beam approach beacon system (BABS) is an automatic radar landing system developed in the early 1940s. [1] It is a responder (or transponder) mounted in a Hillman van and placed at the end of the runway. In some cases fixed sites were installed and by the mid-1950s Standard 9 vans were in use.
The AN-FPQ 6 radar was built by RCA and was, effectively, a development of the AN-FPS 16. The Q6, as it was known by those who worked on it, was an amplitude comparison monopulse C-band radar, with a 2.8 MW peak klystron transmitter tunable from 5.4 to 5.8 GHz, which had a 9-meter parabolic antenna, having 52 dB gain, a 0.6 degree beam width, utilizing a Cassegrainian feed with a five horn ...
