A Modeling Algorithm for Detection of Moving On-water Magnetic Objects

LIN Chun-sheng, XIANG Qian, GONG Shen-guang(Department of Weapon Engineering, Naval University of Engineering, Wuhan, Hubei 430033, China)  
Using the detected signals of a three-axles magnetometer, a real-time EMRES (equable magnetization rotation elliptic-sphere) model can be established. A statistic test algorithm is developed to judge the signals to be from a moving on water magnetic object or not. The magnetic state of the object is also estimated. Experiments show that this technology can detect moving object reliably with low-false alarm probability even if the SNR is lower than zero (dB) and the frequency band of signal and background noise is heavily overlapped, and it also possesses target recognizing ability.
