Abstract:

To solve the problem of anomaly detection (AD) of the non-ideal channel in complex electronic countermeasures, a deep learning based method is presented. First, the feasibility of using time-frequency in-phase/quadrature (I/Q) sampling data for anomaly detection (AD) is analyzed. Then, a deep learning network architecture is designed and an AD method based on deep support vector data description (Deep SVDD) and modulation classification is proposed. Simulation and experimental results show that the detection performance and real-time performance of the method are significantly improved compared with the classical algorithms of one-class classification, and the performance is robust in non-ideal channel environment. The method is validated on a sample machine and is of high application value.

Key words: anomaly detection (AD), deep support vector data description (Deep SVDD), modulation classification, interference warning
