    en.wikipedia.org/wiki/List_of_radar_types

    This radar uses radio waves along with horizontal, dual (horizontal and vertical), or circular polarization. The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor.

    The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.

    ASR-9 was the first Radar System to enable the detection of a moving target with circular polarization, therefore significantly enhancing the ability to locate aircraft in various weather conditions. In addition to the enhanced detection system, six separate weather channels can be switched on to display the precipitation reflectivity measured ...

  8. Radar geo-warping - Wikipedia

    en.wikipedia.org/wiki/Radar_geo-warping

    Radar geo-warping is the adjustment of geo-referenced radar images and video data to be consistent with a geographical projection.This image warping avoids any restrictions when displaying it together with video from multiple radar sources or with other geographical data including scanned maps and satellite images which may be provided in a particular projection.
