基于智能学习的机载海杂波谱参数估计方法

Traditional airborne radar sea clutter suppression methods have a high degree of human participation and large errors in estimating the clutter power spectrum. With the development of modern signal processing and artificial intelligence, deep learning methods are used to study the sea clutter more quickly and intelligently. This paper proposes an airborne radar sea clutter spectrum parameter estimation method based on intelligent learning. It establishes a sea clutter training model based on the one-dimensional LeNet-5. Then the simulated and measured sea clutter data are input into the trained model to estimate the center and width of the power spectrum, thus realizing the direct perception of the sea clutter spectrum characteristics. The experimental results show that the proposed method has a higher estimation accuracy and better robustness than the traditional methods.
