What is the structure of weather radar?

The structure of MST radar is basically the same as that of meteorological Doppler radar. Its characteristic is that large antennas (antenna arrays) are generally installed. Some VHF radars have antenna arrays of 30-200m in size. Half-wave dipole arrays or Yagi antenna dipole arrays are used to realize beam scanning in a phased manner. UHF radar uses a movable parabolic antenna with a diameter of tens of meters. The transmission power of this radar is between several hundred kilowatts and 2 megawatts, and the product value of transmission power and antenna area is between 10 and 10 watt-meter. In addition, in order to obtain high sensitivity and high spatial resolution, some technical measures have been taken in pulse transmission system and echo data processing.
