Abstract
The geometric characteristics and optical properties of ship wake are studied.It is analyzed that the scattering idiosyncrasy of laser by small bubbles in wake which are difficult to diffuse and dissolve in short time.Based on the changes of the forward or backward laser scattering characteristics in time domain,frequency domain and space domain when torpedo comes in and goes out of the ship wake,a new torpedo-wake-homing scheme to shadow the target is proposed.Some laser-wake-homing ways are discussed and compared.It is confirmed that ascending laser-wake-homing means is the advanced non-acoustic wake homing method which not only does not injure the exterior structure of torpedo,but also can fix on the borderline of ship wake by laser scan.
