Inverse Synthetic Aperture Radar produces images which can be trained to recognize by human operators. Because of varying angular motions (roll, pitch, and yaw), the cross-range resolution is produced. So the Automatic Target Recognition (ATR) of ship can be implemented. The centre-line of ship is an important feature. This paper addresses the problem of centre-line detection and length estimation for ship targets. The aim is to calculate the length of ship for recognition. In order to obtain more accurate results, a new analytical model is proposed, the position of mainmast and the differential Doppler concerning the centre-line is used in the estimation the length of ship. The performance of the proposed algorithm is shown by real data and simulated data.
