The invention discloses an umbrella-shaped antenna structure parameter optimization design method based on optimal consistence parameters. The method specifically comprises the following steps: inputting structure parameters and electronic parameters of an umbrella-shaped antenna; calculating segment numbers of antenna ribs; calculating coordinates of points on the ribs; calculating coordinates of points of adjacent ribs; generating all node coordinates of the umbrella-shaped antenna; calculating a node optical path difference direct-ratio vector; calculating a node consistence geometric matrix; calculating a weighting matrix; calculating an optimal consistence parameter column vector; outputting axial precision of the umbrella-shaped antenna; judging whether the axial precision meets requirements or not; outputting the structure parameters of the umbrella-shaped antenna; and updating the structure parameters of the umbrella-shaped antenna. By adopting the umbrella-shaped antenna structure parameter optimization design method, the characteristic that the umbrella-shaped antenna is assembled through surface-piece splicing manner is taken into account, the axial precision of the umbrella-shaped antenna is analyzed based on the concept of an optima consistence paraboloid, the electronic parameters of the antenna are introduced into calculation of the axial precision, and thus the axial precision of the umbrella-shaped antenna is obtained through the optimal consistence parameters; and by adopting the method, mechanical structure design and mechanical-electric integration optimization design of umbrella-shaped antennas can be instructed.
