In order to meet the ignition pulse power requirements for fast ignition, fast ignition drivers being constructed and planned mainly adopt similar technology of segmented primary mirrors as the astronomical telescopes, realizing large-aperture multi-channel laser coherent focusing. Using the geometrical optics tracing and Fourier method to solve the model of tiling focusing, the effect of tiling scale of parabolic mirrors and control precision on focal-spot peak power is studied by theory and numerical simulation. Under certain control precision, the Strehl ratio of far-field focal spot is simulated on 2×2， 3×3 and 4×4 tiling scales of off-axis parabolic mirrors, and the effect of precision error on focal-spot Strehl ratio is statistically analyzed by Monte-Carlo method of normal distr
