PURPOSE:To secure the tracking and capture by forecasting the meeting point permitting the capture of a moving target object in a homing range at a high- speed moving stage of an underwater sailing body to track the target at a high speed to the forecast meeting point without homing. CONSTITUTION:As the homing range is long at the low-speed searching stage of an underwater sailing body 1, a moving target object 2 is detected far with a transmitter 3 and a receiver 4 thereof 1 and the distance, bearing of the target object 2 and a Doppler signal C2 are sent to a control panel 5, which receives changes in the signal C2 with time, absolute coordinates (x0, y0, z0) and the velocity VG of the sailing body 1 from an inertial guidance device 7 and changes of direction with time to obtain the velocity VT, mark angle At and distance Ro of the target object 2. Then, the control panel 5 forecast the meeting point of capturing the moving target object 2 at the center of the homing range at a tracking velocity from the velocity VT, the mark angle At and the distance Ro of the target object 2 and the velocity VG of the underwater sailing body 1 and the distance RL in the half of the homing range at the tracking velocity to determine an anticipated angle Aa and arrival time Ta when the meeting point is reached by computation according to a specified formula. |
