in the rear of a surface ship is generated along the track of surface ships. In this paper, we assume that the nearer
the surface ship, the stronger wake strength is and a two-sensor based wake homing torpedo can sense for the wake
strength. On this assumption we propose a simple wake detection and search method using information of wake
strength. Experimental results using monte-carlo simulation demonstrate that the proposed method yields better
performance in search time than previous method, which uses a single sensor. Our method is shown faster by about
45 seconds than previous method to achieve the same performance. Also, it can improve the detection performance
of torpedo in the case of short wake length.
