摘要：

In order to reduce the calculation burden of the signal number estimation and improve the accuracy against the background of small snapshots, an idea for counting signal numbers based on a support vector machine is provided. First, the features of the signal and noise are extracted by the orthogonality between the noise vector and the array manifold. Then, a classifier based on a support vector machine is designed. Finally, the optimal structure of the classifier and the corresponding coefficients are trained by theoretical analysis and training data. The proposed algorithm performs well in both Gaussian white noise and colored noise. The validity and feasibility of the proposed theory are verified by the simulations. © 2020 Totem Publishers Ltd.
