- Nota adicional1
- The general qualifications for weather radars are 1) a wavelength between 1 and 30 cm, 2) pulsed transmission with high peak power (kilowatts to megawatts), 3) relatively narrow beamwidths, 4) pulse lengths of a few microseconds or less, 5) pulse repetition frequencies of several hundred hertz, and 6) automatic azimuth or elevation angle scanning. Electronic circuits and signal processing permit the quantitative measurement of radar reflectivity factor or signal strength and, for Doppler radars, the radial velocity.
- Contexto
- Some meteorological information, such as processed weather radar and satellite data, tropical cyclone and volcanic ash advisory information, and wind shear warnings and alerts, may be supplied to ATS units in graphical format, as agreed between the meteorological and ATS authorities concerned.
