  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. Aviation transponder interrogation modes - Wikipedia

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

    Upon interrogation, Mode S transponders transmit information about the aircraft to the SSR system, to TCAS receivers on board aircraft and to the ADS-B SSR system. This information includes the call sign of the aircraft and/or the aircraft's permanent ICAO 24-bit address (which is represented for human interface purposes as six hexadecimal ...

  4. Air traffic control radar beacon system - Wikipedia

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

    An ATC ground station consists of two radar systems and their associated support components. The most prominent component is the PSR. It is also referred to as skin paint radar because it shows not synthetic or alpha-numeric target symbols, but bright (or colored) blips or areas on the radar screen produced by the RF energy reflections from the target's "skin."

  5. Perimeter surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Perimeter_Surveillance_Radar

    Perimeter surveillance radar (PSR) is a class of radar sensors that monitor activity surrounding or on critical infrastructure areas such as airports, [1] seaports, military installations, national borders, refineries and other critical industry and the like. Such radars are characterized by their ability to detect movement at ground level of ...

  6. Primary radar - Wikipedia

    en.wikipedia.org/wiki/Primary_radar

    A primary radar or primary surveillance radar (PSR) is a conventional radar sensor that illuminates a large portion of space with an electromagnetic wave and receives back the reflected waves from targets within that space. The term thus refers to a radar system used to detect and localize potentially non-cooperative targets.

  7. Precision approach radar - Wikipedia

    en.wikipedia.org/wiki/Precision_Approach_Radar

    AN/TPN-12 GCA/PAR. A traditional PAR flight inspection procedure is performed without a navigation signal available to compare directly to a truth reference. A traditional PAR is flight inspected by comparing written notes between two observers, one taking notes at a truth reference system such as a theodolite and the other observer taking notes while observing the radar console; see ICAO ...

  8. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    The klystron tube transmitter operates in the S-band between 2.5 and 2.9 GHz in circular polarization with a peak power of 1.3 MW and a pulse duration of 1 μs and pulse repetition frequency between 325 and 1200 pps. It can be switched to a second reserve frequency if interference is encountered on the primary frequency.

  9. SASS-C - Wikipedia

    en.wikipedia.org/wiki/SASS-C

    The functionality comprises decoding (one between many, ASTERIX data format), recording and computation of statistics. TRES (Trajectory Reconstruction and Evaluation Suite) is the core suite of SASS-C, carrying out the reconstruction of reference trajectories from the input data, and doing the evaluation of Surveillance constituent's performance.
