Under special condition, the surface target could be attacked by the submarine with two wire-guided torpedoes with passive acoustic homing mode. When the acoustic homing device detects the target bearing and transmit it back to the submarine through the wire, a three-sensor detection system is constituted by the submarine’s integrated sonar and the two wire-guided torpedoes. Whether the system can effectively track the target is related to the observability of the system. Only by satisfying the observable conditions can the moving parameters of the target could be calculated. For the nonlinear characteristics of the two wire-guided torpedoes tracking system, the observation equation is treated by pseudo-linear processing, and then the observability of the linear system is analyzed by using the observability decision theorem of the linear system, then the conditions for judging the observability are given. Finally, the correctness of the conclusion is verified by simulation.
