(一)导弹的导引和控制原理导弹与炮弹和火箭的不同点在于:炮弹和火箭在点火瞬间就付予了一定的航向,而导弹的航向在飞行期间是可变的。为了有效地将导弹引向目标,必须连续地解决导弹火控问题。为此,必须完成四项任务:①跟踪,②计算,③导引,④控制。为完成所有这些任务所必需的部件可以全部装在导弹本身,或者某些部件装在载机上。很难把火炮、火箭的火控问题与导弹控 I. The Guidance and Control Principles of Missiles The difference between missiles and artillery shells and rockets lies in the fact that artillery shells and rockets are paid a certain course at the moment of ignition, and the course of the missiles is variable during the flight. In order to effectively guide missiles to the target, the issue of missile fire control must be solved continuously. To do this, four tasks must be completed: ① tracking, ② calculation, ③ guidance, ④ control. The components necessary to accomplish all of these tasks can be mounted entirely on the missile itself, or on the carrier. It is difficult to control artillery, rocket fire control and missile control
