    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 ...

    en.wikipedia.org/wiki/Air_traffic_control_radar...

    The primary surveillance radar is subject to the radar equation that says signal strength drops off as the fourth power of distance to the target. Objects detected using the PSR are known as primary targets. The second system is the secondary surveillance radar, or SSR, which depends on a cooperating transponder installed on the aircraft being ...

  4. Radar tracker - Wikipedia

    en.wikipedia.org/wiki/Radar_tracker

    Track initiation is the process of creating a new radar track from an unassociated radar plot. When the tracker is first switched on, all the initial radar plots are used to create new tracks, but once the tracker is running, only those plots that couldn't be used to update an existing track are used to spawn new tracks.

    The ASR-9 was the first airport surveillance radar to detect weather and aircraft with the same beam and be able to display them on the same screen. It has a digital Moving Target Detection (MTD) processor which uses doppler radar and a clutter map giving advanced ability to eliminate ground and weather clutter and track targets. It is ...

    The first system developed by the Czech army in 1963 was known as PRP-1 Kopáč which could track 6 targets. This was followed by KRTP-81 Ramona (NATO reporting name Soft Ball) in 1979, which could track 20 targets, and KRTP-86 Tamara (NATO reporting name Trash Can) in 1987, which could simultaneously track 23 radar targets and 48 IFF targets.

  8. Track algorithm - Wikipedia

    en.wikipedia.org/wiki/Track_algorithm

    Track algorithm operation depends upon a track file, which contains historical track data, and a computer program that periodically updates the track file. [3] Sensors information (radar, sonar, and transponder data) is provided to the track algorithm using a polar coordinate system, and this is converted to cartesian coordinate system for the ...

  9. Aviation transponder interrogation modes - Wikipedia

    en.wikipedia.org/wiki/Aviation_transponder...

    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.
