一、引言空中射击时,为了使弹丸命中目标,应该构成提前角、抬高角、迎角及侧滑带偏修正角。在采用三自由度电磁陀螺仪的射击瞄准具里,构成提前角的工作式是:Ψ=(ω_M-K_(?))T_(?) (1)式中ω_M 是目标线角速度,由三自由度电磁陀螺仪测量;T_(js)是取决于射击条件和弹丸道特性的计算时间,T_(?)是经动态补偿 I. Introduction Aerial shooting, in order to make the projectile hit the target, should constitute the advance angle, elevation angle, angle of attack and side slip belt partial correction angle. In the shooting sights with three degrees of freedom electromagnetic gyroscope, the working formula that forms the advance angle is: ψ = (ω_M-K _ (?)) T_ (?) Where ω_M is the target angular velocity, Degree of electromagnetic gyroscope measurement; T_ (js) is dependent on the shooting conditions and the trajectory of the ballistic characteristics of the calculation time, T_ (?) Is dynamically compensated
