A robust estimation method of ship target attitude angle based on radar track

This paper presents a new method to extract the characteristics of ship attitude angle by using radar track information. Firstly, the ship motion model is established, and then the track data is preprocessed. After that the motion state of ship is estimated, and the curve is simulated by the M-estimator method. Finally, the attitude angle of ship is estimated. The experiment results show that the method is robust and estimate attitude angle of ship effectively. Therefore it has a great application value in engineering.
