Abstract:

In modern battlefield environments, radar target recognition faces dual challenges: the difficulty in acquiring datasets for advanced targets and the high demand for interpretability for decision-making. To address these issues, a fuzzy probabilistic pattern recognition method, based on the statistical properties of high-resolution range profiles features, is proposed by integrating the high-precision advantages of statistical pattern recognition with the noise-resistant characteristics of fuzzy pattern recognition. In terms of statistical properties, the χ2 distribution is extended to a generalized p-norm, allowing for a comprehensive investigation and analysis of the statistical properties of the χ p distribution to achieve higher recognition accuracy. In terms of fuzzy attributes, a membership function is utilized, enabling the proposed method to maintain good recognition performance even under low signal-to-noise ratio conditions. Data generation for advanced foreign fighter aircraft is conducted using the electromagnetic simulation software. The experimental results indicate that the proposed method outperforms existing pattern recognition technologies in both identification accuracy and noise robustness.

Key words: radar target recognition, high resolution range profile (HRRP), pattern recognition, feature extraction, fuzzy probability
