Target Detection Method in BTR based on SVM

Aiming at the problem of low SNR in complex sea conditions, which leads to low target detection rate and robustness in BTR, a BTR target detection method based on SVM is proposed. The method uses the waveform difference between target and noise in spatial domain to give the feature description; In this paper, SVM is used to train BTR target detection model; The underwater acoustic target point trace detection is completed by region-to-point trace extraction method. The experimental results show that the proposed method can extract underwater acoustic targets in low SNR effectively and robustly.
