Low-altitude low-speed small target threat assessment method and system based on LSTM model in combination with KAN network

Abstract

The invention discloses a low-altitude low-speed target threat assessment method and system based on an LSTM model in combination with a KAN network, and the method comprises the following steps: S1, obtaining low-altitude low-speed target pulse data in a set time period, and taking the pulse data with the length of N as a sample for preprocessing; s2, preprocessing the pulse data in a fuzzy data mode; s3, constructing a model based on an LSTM model in combination with a KAN network, and initializing parameters; s4, processing according to the credibility of the data, inputting the processed data into the model constructed in the step S3 for network training, and storing the weights of the feature extractor and the classifier obtained by training; and S5, preprocessing pulse data of the low-altitude low-speed target to be measured, and inputting the preprocessed pulse data into the model trained in the step S4 for evaluation to obtain a threat evaluation result of the low-altitude low-speed target. According to the method, the threat assessment accuracy of the low-altitude low-speed small target can be improved in a dynamic environment.
