The magnetic anomaly created by ferromagnetic ships may endanger their invisibility. Nowadays, a new technique called closed-loop degaussing system can reduce the magnetic anomaly especially permanent one in real-time. To achieve it, a model able to predict off-board magnetic field from onboard measurements is required. Many researchers settle the problem by some numerical models. In this paper, we...
Acoustic wave signals, radiated from moving vehicles, can be used for automatic vehicle classification as an effective source of information. Acoustic wave signals are processed by self-correlation analysis in frequency domain based on Welch spectrum estimation. Original feature vectors of the linear power spectrum are obtained. Principal component analysis (PCA), aiming to reduce data dimension,...
