  2. Secondary surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Secondary_surveillance_radar

    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 ...

  3. 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.

  4. Air traffic control radar beacon system - Wikipedia

    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 ...

    Radar range and wavelength can be adapted for different surveys of bird and insect migration and daily habits. They can have other uses too in the biological field. "MERLIN Avian Radar System for Bird Activity Monitoring and Mortality Risk Mitigation" (PDF). Insect radar. Surveillance radar (mostly X and S band, i.e. primary ATC Radars)

  6. 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.

  7. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    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 ...

  8. Track while scan - Wikipedia

    en.wikipedia.org/wiki/Track_while_scan

    The drawback is that once the radar is set to tracking a single target, the operator loses information about any other targets. This is the problem that track while scan is meant to address. In traditional radar systems, the display is purely electrical; signals from the radar dish are amplified and sent directly to an oscilloscope for display ...

  9. National Track Analysis Program - Wikipedia

    en.wikipedia.org/wiki/National_Track_Analysis...

    The National Track Analysis Program (NTAP) can identify and track targets which are at a sufficient altitude to be tracked by radar whether or not they are being "controlled" by the ARTCC. NTAPs requested by the AFRCC have proven to be very helpful during an aircraft search by providing the route of flight and last radar position of an aircraft ...
