  2. 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.

  3. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    The sophisticated systems at large airports consist of two different radar systems, the primary and secondary surveillance radar. [1] The primary radar typically consists of a large rotating parabolic antenna dish that sweeps a vertical fan-shaped beam of microwaves around the airspace surrounding the airport. It detects the position and range ...

    Insect radar. Surveillance radar (mostly X and S band, i.e. primary ATC Radars) Tracking radar (mostly X band, i.e. Fire Control Systems) Wearable radar and miniature radar systems are used as electric seeing aids for the visually impaired, as well as early warning collision detection and situational awareness

    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 ...

    en.wikipedia.org/wiki/ASR-11

    This radar system consists of two separate electronic subsystems, the first being a primary radar and the other, a secondary surveillance radar often referred to as the beacon. Like the ASR-9, the ASR-11 uses a continuously rotating antenna that is mounted on a tower.
