The invention discloses an aircraft trajectory prediction method based on an LSTM-DNN hybrid neural network, and relates to the field of civil aircraft trajectory prediction, and the method comprises the following steps: S1, screening aircraft trajectory prediction model input, collecting ADS-B data, and processing missing data through a data fitting method; s2, predicting a future flight trajectory by using an LSTM long and short term prediction model; s3, adopting a DNN deep feedforward neural network model to predict the flight path deviation of the next time point; s4, using the prediction result of the high-precision model to correct the prediction result of the low-precision model; and S5, according to a trajectory prediction result, adopting a separation distance to indicate the flight safety of the two flights at the future moment. By adopting the above steps, two neural network models are constructed, the deviation between the actual flight path and the target flight path and the long-term prediction of the future flight path are respectively predicted, the prediction results of the two models are fitted together through the error term, and the long-term high-precision prediction of the flight path is realized.
