The relationship between the wire\|guided homing trajectory characteristic and the guidance law of wire\|guided torpedo is got to be clear and definite. By analysing the dynamics in the common guidance laws of wire\|guided torpedo, i.e., the matching\|curve guidance and the lead\|angle guidance, the formulas of torpedo turning rate under different guidance laws are calculated. In the course of direct digital simulations, the wire\|guided homing trajectories of wire\|guided torpedo are emulated by using of matching\|curve guidance and lead\|angle guidance. Thus, the dynamic characteristics are discussed.
