Spherical dual-polarization phased array weather radar

A spherical dual-polarization phased array weather radar system, the system comprising:

• a spherical crown phased array antenna module including a spherical support frame and a plurality of dual-polarization micro-strip radiation units, the dual-polarized micro-strip radiation units being tightly arranged on the spherical support frame, and the positions of the dual-polarized micro-strip radiation units are adjusted, so that the directions of beams emitted by the dual-polarized micro-strip radiation units are consistent with the normal directions of effective apertures of the spherical support frame;
• a digital transceiver module configured to generate a frequency modulation signal or a phase coding signal required for detecting meteorological targets and receive an echo signal reflected by the target and transmit information wirelessly with the spherical crown phased array antenna module;
• and
• a signal processing module is connected with the digital transceiver module,
• wherein the adjusted dual-polarization micro-strip radiation units are configured to send out the beams according to the frequency modulation signal or the phase coding signal, detect the meteorological targets and send the echo signal to the digital transceiver module,
• the digital transceiver module is configured to send the echo signal to the signal processing module, and
• the signal processing module is configured to perform spectral analysis on the echo signal to obtain target echo information.
