We research into the locomotive state and the connection on kinetics that the system of a mine launching by a active exhaust in deep-water is moved because of the force produced by an undercurrent and the mine launch.

In counter intellectual helicopters,ordinary-minds are mainly detecting and attacking targets, while the main-mines are functionally different.

For the purpose of improving torpedo trajectory simulation level,this paper introduces the method to associate 3D visualization simulation technology and high level architecture(HLA) distributed simulation standard with traditional torpedo trajectory simulation,and uses the softwares Creator and Vega as assistant tools.

Though we have make much progress on it, there remains many problems to study deeply, of which its supporting software system developing is an important and elementary subject of torpedo trajectory research.

The models of the torpedo trajectory simulation software based on WISE (Weapon system Integration Simulation Environment) were modularized according to the logic sequence of torpedo trajectory and the function of torpedo subsystem.

Aimed at the angle legging defect existed in the acoustic location of high speed moving object by smart mine,the estimate of object flying track and coefficient recursion algorithm in flying module are developed in the paper.

Aimed at the problem of low elevation angle precision under the condition of plane array and small elevation angle of smart mine′s passive acoustic detection,high-low quaternion array is brought forward,and the locating algorithm of the array is deduced.

After the placement of the smart mine,the early-warning system starts on working,it must keep detecting and recognizing,so it is high power-consume,in order to maintain its ability of inspection and defense,it must be a low power system.
