  2. Radar signal characteristics - Wikipedia

    en.wikipedia.org/wiki/Radar_signal_characteristics

    Sea clutter can be reduced by using horizontal polarization, while rain is reduced with circular polarization (note that meteorological radars wish for the opposite effect, and therefore use linear polarization to detect precipitation). Other methods attempt to increase the signal-to-clutter ratio.

  3. List of radar types - Wikipedia

    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.

  4. Nebo-M - Wikipedia

    It is the successor to the old 1L13 Nebo “Box Spring” radar and is easy to distinguish from it as the direction of polarization is vertical rather than horizontal. It has a range of 600 km (370 mi) and can track objects flying as fast as Mach 6.4. RLM-M Radar

  5. Radar - Wikipedia

    en.wikipedia.org/wiki/Radar

    Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.

  6. Polarization (waves) - Wikipedia

    Now if one were to introduce a phase shift in between those horizontal and vertical polarization components, one would generally obtain elliptical polarization [12] as is shown in the third figure. When the phase shift is exactly ±90°, and the amplitudes are the same, then circular polarization is produced (fourth and fifth figures).

  7. Radar engineering - Wikipedia

    en.wikipedia.org/wiki/Radar_engineering

    Polarization (antenna): The polarization of ground-based radar sensors is vertical, in order to reduce multipath (Brewster angle). Radar sensors can also be polarimetric for all-weather applications. Radar sensors can also be polarimetric for all-weather applications.

  8. Weather radar - Wikipedia

    en.wikipedia.org/wiki/Weather_radar

    Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).

  9. E-plane and H-plane - Wikipedia

    en.wikipedia.org/wiki/E-plane_and_H-plane

    The electric field or "E" plane determines the polarization or orientation of the radio wave. For a vertically polarized antenna, the E-plane usually coincides with the vertical/elevation plane. For a horizontally polarized antenna, the E-Plane usually coincides with the horizontal/azimuth plane. E- plane and H-plane should be 90 degrees apart.
