The invention discloses a
data transmission method of a digital
phased array, particularly relates to the field of communication transmission, and is used for solving the problem that configuration change effective boundaries of multiple receiving ends are inconsistent under the condition of out-of-order links. Sampled data is packaged into a data frame written with a
frame sequence number and frame integrity
verification information through a sending end, the data frame is sent according to the
frame sequence number, and a barrier frame written with a barrier sequence number is inserted before configuration change; after entering a barrier freezing state, a receiving end records a barrier drop point
frame sequence number and a continuous
tail frame sequence number, generates a neighborhood frame sequence event string and sends a barrier
receipt; the sending end forms submission judgment according to the barrier
receipt, determines a uniform submission frame sequence number and then sends a submission frame written with the configuration version number and the uniform submission frame sequence number; and the receiving end writes the new configuration into the to-be-submitted area, loads and takes effect when the frame number of the data frame reaches the uniform submission frame number, and returns a submission
receipt.
