  2. Circular error probable - Wikipedia

    en.wikipedia.org/wiki/Circular_error_probable

    Circular bivariate normal distribution 20 hits distribution example. The original concept of CEP was based on a circular bivariate normal distribution (CBN) with CEP as a parameter of the CBN just as μ and σ are parameters of the normal distribution.

  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. ASR-9 - Wikipedia

    en.wikipedia.org/wiki/ASR-9

    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 ...

    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.

  6. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    It is a relocatable, solid-state, all-weather radar with dual-channel, frequency diversity, remote operator controls, and a dual beam tower mounted antenna. The radar provides controllers with range azimuth of aircraft within a 60 nautical mile radius. ASR 8 used a klystron as transmitters power amplifier stage with a load of 79 kV and 40A.

    A Doppler radar is a specialized ... This variation gives direct and highly accurate measurements of ... This was made possible by the use of circular polarization ...

  8. Radar display - Wikipedia

    en.wikipedia.org/wiki/Radar_display

    A radar display is an electronic device that presents radar data to the operator. The radar system transmits pulses or continuous waves of electromagnetic radiation , a small portion of which backscatter off targets (intended or otherwise) and return to the radar system.

  9. AN/FPS-16 Instrumentation Radar - Wikipedia

    en.wikipedia.org/.../AN/FPS-16_Instrumentation_Radar

    The C-Band Radar Transponder (Model SST-135C) is intended to increase the range and accuracy of the radar ground stations equipped with AN/FPS-16, and AN/FPQ-6 Radar Systems. C-band radar stations at the Kennedy Space Center, along the Atlantic Missile Range, and at many other locations around the world, provide global tracking capabilities.
