description | The invention relates to a Beidou satellite signal high-precision capture model based on blind separation of variance ratio. By means of a blind separation technique and a frequency multiplication sampling method, the Beidou satellite signal high-precision capture model based on blind separation of variance ratio establishes a blind separation matrix satellite signal model by using the Euler's formula after serialization of channels, and performs blind separation on satellite signals by means of subspace separation, wherein the concrete implementation steps includes: S1, converting a satellitesignal received by a receiver into an aliasing sinusoidal model output by multiple channels by using the frequency multiplication sampling method; S2, serializing the satellite receiving signal; S3,unfolding a satellite carrier signal hsat(j) after frequency multiplication sampling into a blind separation matrix model by using the Euler's formula; S4, solving the Doppler effect frequency of thesatellite carrier signal; S |
