In order to test laser beam riding guidance information field,this paper introduces the design scheme and principle of the testing system in detail according to parameters of information field.

General hierarchy and basic method of the efficiency evaluation of vehicular anti-tank missile weapon system are discussed at length.

Aiming at the phenomenon of anti-tank missile can not hit the goal after the missile launched,the failure mode that the missile falls down in short distance,flies high in long distance and undershoot were studied,and then the failure mode was presented.

The indoor launching characteristics of anti-tank missile and the possibility of injury to firers were analyzed systematically.

The reasons of deflection when the antitank missile is under lean firing were presented;and mathematical model of ballistic deflection was built to give quantitative analysis for ballistic deflection when the antitank missile lean firing.

Based on the aerodynamic configuration of New Javelin light antitank missile, a series of wind tunnel experimental model was designed with the component build-up method.

According to the general program of a portable antitank missile steering to hit on top of the tank at terminal trajectory, this paper presented the closed-loop control stiffness ballistic model and simulation for the straight flight, the glancing flight and terminal steering trajectory under both the fixed and active targets.
