Embodiment Construction
[0061] In view of the above background and problems, the present invention aims to provide a method for realizing aircraft trajectory prediction by using a long-short-term memory network (LSTM) under uncertain perception conditions. For the noise interference of the sensor feature vector, Kalman filtering is used to eliminate it; for the directly obtained state parameters, data preprocessing is performed on it, including downsampling, invalid value elimination, and missing value complement. In addition, in order to improve calculation stability The data is normalized, and the value range of the input data is included in the [0,1] interval; the trajectory prediction model based on LSTM is constructed, the input and output of the network are defined, and the network is supervised and trained.
[0062] Function and characteristics of the present invention are as follows:
[0063] (1) Under the actual air combat environment, the present invention has the characteristics of interac...
