Title The Research of Speed and Position Measurement System of Rotating Projectile Body
Abstract
With the development of intelligent ammunition technology, there is a high demand
an the rotating speed and angular position. In terms of the rotating speed of the projectile body,the scale is from 3000r/min to 20000r/min.Aming at the measurement of angular position under high rotating speed,this article presents a way using double spin structure to calculate the angular position.Using the single chip microprocessor STM32 as the major control unit with the multi-periods pulse synchronization method gives an acceptable result.At the first step, we designed the hardware circuits,the sensor signal is passed to the MCU after the signal conditioning circuits and the filter circuits.With some algorithm,the rotating speed and the angular position can be carried out.This paper gives the whole designing process of the rotating speed and position measurement system as well as the experiments.In the final part of this paper,it gives the data analysis about the experiments.The result proves that the method is acceptable for the giving resolution requirements and it can gain the angular position successfully.

1.1 课题研究背景
随着科学技术的进步，未来战争样式以及作战环境都将有很大的变化。这促使武器装备的更新换代，并对其攻击性能、制导性能等提出了更高的要求。很多低成本的武器采用稳态控制的滚动模式，具有操作简单，发射后不管的特点[ ]。然而这种武器的制导受到严重的限制，必然会被新型的精确制导武器替代。
