The application relates to an antenna
phase center calibration method and
system based on minimum PCV deviation constraints, which comprises the following steps: determining the equivalent conversion relationship of a
phase model according to the
coupling of PCO and PCV; determining the optimal constraint condition; converting the original model into an equivalent
phase model according to the optimal constraint condition; constructing virtual observation values for
simulation positioning test, which comprises the following steps: constructing virtual observation values by using a first model in a virtual coordinate
system, correcting by using another model, then using a least square method for
single point positioning calculation to calculate the positioning error in the north-east-high direction; verifying the coordinate
estimation of the
simulation positioning test and the difference between the converted
phase model PCO with the constraint condition, and outputting the antenna
phase center calibration result. The application has the advantages that on the basis of considering the PCO / PCV
coupling, additional constraint conditions are added to convert the compared phase models, the
workload of phase model comparison is reduced, and the influence of the phase model difference on positioning is more directly reflected.
