SSR antenna of Deutsche Flugsicherung at Neubrandenburg, in Mecklenburg/Western Pomerania Transponder in a private aircraft squawking 2000. Secondary surveillance radar (SSR) [1] is a radar system used in air traffic control (ATC), that unlike primary radar systems that measure the bearing and distance of targets using the detected reflections of radio signals, relies on targets equipped with ...
The curved reflector antenna on the bottom is the primary surveillance radar (PSR), and the flat antenna on top of it is the secondary surveillance radar (SSR). In operation the antenna rotates about a vertical axis, sweeping a vertical fan-shaped beam of microwaves around the local airspace to locate and track aircraft.
The secondary surveillance radar consists of a second rotating antenna, often mounted on the primary antenna, which interrogates the transponders of aircraft, which transmits a radio signal back containing the aircraft's identification, barometric altitude, and an emergency status code, which is displayed on the radar screen next to the return ...
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.
A visual representation of a vertical antenna's blind cone. In telecommunications, antenna blind cone (sometimes called a cone of silence or antenna blind spot) is the volume of space, usually approximately conical with its vertex at the antenna, that cannot be scanned by an antenna because of limitations of the antenna radiation pattern and mount.
Primary radar operation is based on the principle of echolocation. Electromagnetic pulses of high power emitted by the radar antenna are converted into a narrow wavefront which propagates at the speed of light (300 000 km/s). This is reflected by the aircraft and then picked up again by the rotating antenna on its own axis.
