Improvements in SSR

Abstract

Developed from a wartime indentification system, Secondary Surveillance Radar (SSR) has become a means whereby the air traffic controller can be provided with an immediate display of an aircraft's identity, range, azimuth and height. Also, since SSR is a communication channel, further special information can be supplied such as indication of in‐flight emergency communications failure or the detection of a “hi‐jack” situation.
