Vehicle-mounted scatter communication antenna system and antenna alignment method

The invention discloses a vehicle-mounted scatter communication antenna system and an antenna alignment method, and relates to the field of scatter communication. The method comprises the following steps: by taking a synchronous orbit satellite as a reference, calculating errors of a pitch angle, an azimuth angle and a polarization angle when a local-end vehicle-mounted scatter communication antenna communicates, and performing error correction when the local-end vehicle-mounted scatter communication antenna communicates with an opposite-end vehicle-mounted scatter communication antenna; the system specifically comprises a reference clock module, a modem, an up-converter, a high-power amplifier, a scattering duplexer, a polarization adjustable parabolic antenna and servo mechanism, a scattering LNA, a down-converter, a Beidou host module, a satellite receiving filter, a satellite receiving LNB, a level detection module and a centralized control module. According to the method, the complexity of station type u
