为了对火箭弹实施某种控制以达到减小火箭弹射弹散布和增加射程的目的，需要实时测量火箭弹的滚转角速度。针对远程旋转火箭弹，提出了一种基于短波信号进行转速测量的设想。通过分析推导，给出了感应电动势与弹体运动关系；探讨了利用近垂直入射天波传播NVIS天线解决短波通信静区的问题的可行性；对弹载短波接收天线采用铁氧体加载螺旋线圈天线，进行设计和仿真，在理论上解决了短波天线难以微型化置入弹内的问题。

To lower the shell distribution and to extend the range of rocket, a nozzle-like rocket-bounded actuator is deliberately designed to alter the outer trajectory. Real-time measure ment of rocket rotation angle is needed to help the actuator act at the precise time. The thesis presents a method of using shortwave signals to measure the rotating speed of tong range rocket projectile. In this thesis a thorough study of the relation between geomagnetic induction voltage and the movement of the rocket is conducted, and utilizing the NVIS antenna to clear up the dead zone of short-wave communication. The ferrite loading the spiral coil antenna installed on the rocker projectile to receive short-wave signal can solve the problem when the short wave is not small enough to be set in the rocker projectile in theory.
