| description | The invention discloses a method for maintaining the phase coherence of a transmitter and a plurality of receivers, which is characterized by comprising the following steps: adding a compensation stage in a pulse sequence; switching frequencies of all receivers to an excitation frequency at an excitation stage of the pulse sequence; switching the frequencies of all the receivers to respective sampling frequency at a data sampling stage; and switching the frequencies of all the receivers to sampling frequencies of other receivers sequentially at the compensation stage. The frequencies of all the receivers are identical at other stages of the pulse sequence; and a frequency of the transmitter is always identical with that of one of the receivers in an implementation period of the pulse sequence. The method can ensure the phase coherence of the transmitter and the plurality of receivers simultaneously; moreover, the influence of rounding errors of the frequencies of the transmitter and the receivers on phases ar |
