Target Recognition of RCS Sequence Based on Neural Network

The threat of space targets is moving toward the diversification of attack forms and the speed of warfare. It is urgent to carry out research on space target monitoring and identification technology. The radar cross-sectional data is obtained by moving the spatial target along the orbit relative to the measured radar attitude, and the target stable state can be roughly inferred after the data processing, thereby constructing the target template library. In this paper, a neural network-based RCS sequence target recognition method is presented. The scheme of constructing the attitude angle template library by the angle between the radar line of sight and the target radial axis and tangential axis is proposed. Through feature extraction and classifier design, the 18-dimensional feature vector is composed of 18 features, and the neural network classifier is used for training and classification. The recognition accuracy of a sliding window processing can reach 96.77%, which achieves the ideal effect.
