  2. Ka band - Wikipedia

    en.wikipedia.org/wiki/Ka_band

    Radio bands. The Ka band (pronounced as either "kay-ay band" or "ka band") is a portion of the microwave part of the electromagnetic spectrum. The designation "K a -band" is from Kurz-above, which stems from the German word kurz, meaning "short". [1] There is no standard definition of Ka-band. IEEE Standard letter designations for Radar Bands ...

    en.wikipedia.org/wiki/Radar_detector

    A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding. In general sense, only emitting technologies, like doppler RADAR, or LIDAR can be detected.

  4. K band (IEEE) - Wikipedia

    en.wikipedia.org/wiki/K_band_(IEEE)

    The IEEE K-band is a portion of the radio spectrum in the microwave range of frequencies from 18 to 27 gigahertz (GHz). The range of frequencies in the center of the K-band between 18 and 26.5 GHz are absorbed by water vapor in the atmosphere due to its resonance peak at 22.24 GHz, 1.35 cm (0.53 in). Therefore these frequencies experience high ...

  7. Millimeter cloud radar - Wikipedia

    en.wikipedia.org/wiki/Millimeter_cloud_radar

    Millimeter-wave cloud radars, also denominated cloud radars, are radar systems designed to monitor clouds with operating frequencies between 24 and 110 GHz (Table 1). Accordingly, their wavelengths range from 1 mm to 1.11 cm, about ten times shorter than those used in conventional S band radars such as NEXRAD.

    RBS 23. The RBS 23, designated BAMSE (Bofors Advanced Missile System Evaluation), is a Swedish medium range, all-weather capable air defense system developed by Bofors and Ericsson Microwave Systems (now both in the Saab group). BAMSE is designed for protection of military facilities, ground forces and high value infrastructures.
