Abstract：An ionospheric profile with increasing error or even fault will be caused by the missing of large number of data,or taking no propagation feature into account in the data interpolation,in the overlapping polynomial inversion.In the paper,an improved method for the profile inversing is presented with emphasis on data preprocessing.In this method,an ionospheric model is constructed from theory,and the missing data are compensated with the measured virtual heights.Then,the whole profile inversion is realized with the overlapping polynomial model through searching and iterating algorithm.The method is tested with real data and a more reasonable results with physical meaning is obtained.The effectivity of the proposed method is further verified with the synthesized virtual heights from inversing results comparing with that of the measured.
