Brit.

/ˈʃɔːran/,

/ˈʃɒran/, U.S.

/ˈʃɔˌræn/

Forms: Also Shoran.

Etymology: < the initial letters of short-range navigation.

Originally U.S.

A secondary radar system, used for precision navigation and for distance measurement, in which an aircraft or ship determines its distance from two widely-spaced ground stations which it interrogates alternately with radio pulses. Frequently attributive. Cf. Loran n.

1946 N.Y. Times 28 Apr. 1/3 Those who have..tested shoran call it ‘perhaps the greatest single invention of its type for long-range mapping to come from the family of radar in the war’.

1946 Trans. Amer. Geophys. Union XXVII. 459 Basically, the shoran equipment consists of three main units, the airborne transmitter-receiver-indicator and the two ground station transponders.

1949 Sun (Baltimore) 2 Mar. 13/2 What prompted the use of the Superforts was the belief that the development of Shoran (Short Range Navigation) equipment had reached the point where it could be put to work for the astronomer.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) IX. 18/2 The single-path round-trip system is the basis of distance determination in all radars. It is the system employed by Benito, Condar, Oboe, shoran, and the distance-measuring portion of Tacan equipment.

1970 Canad. Cartographer VII. 23/1 12 shoran ground stations.

1977 Sci. Amer. Oct. 92/3 At each one a transponder was set up for a shoran radio-positioning system.
