The invention provides a flight verification evaluation method for a microwave landing system, and aims to solve the problem that the spatial resolution of collected data is insufficient in the MLS flight verification process, the method employs a radial basis function neural network interpolation method to carry out the post-processing of sparse data collected in flight verification, employs the collected sparse data as a training set, and achieves the evaluation of the flight verification of the microwave landing system. High-precision interpolation is realized in a three-dimensional space, and inversion reconstruction of an MLS three-dimensional space signal field pattern is realized, so that an MLS complete space signal field pattern is evaluated. According to the MLS flight verification evaluation method provided by the invention, a large number of tedious flight subjects are not needed, and the accuracy and efficiency of MLS flight verification are improved. 本发明提供一种微波着陆系统飞行校验评估方法，针对MLS飞行校验过程中采集数据空间分辨率不足
