为消除非零位拼接检测非球面中对准误差对拼接结果的影响,建立了基于对准误差修正的优化拼接模型;在非零位检测非球面对准误差模型的基础上,分析对准误差各误差分量的表现形式及影响规律,并建立了基于对准误差补偿的拼接检测非球面的数学模型,实现子孔径的高精度拼接合成。实验表明,该方法可以有效地提高拼接测量精度,经过对准误差校正的拼接测量结果的PV值精度可达0.03λ。 In order to eliminate the influence of misalignment in non-zero position detection on the result of splicing, the optimal splicing model based on the alignment error correction was established. On the basis of the non-zero position detection aspheric alignment error model, Error of the error of the components of the form and the impact of law, and established based on the alignment error compensation splicing detection of aspheric mathematical model to achieve high-precision sub-aperture splicing synthesis. Experiments show that this method can effectively improve the accuracy of the splicing measurement. The accuracy of the PV value of the spliced ​​result after alignment error correction can reach 0.03λ.
