基于短波信号的远程火箭弹转速探测方法的研究

本文提出一种采用短波信号进行远程火箭弹转速测量的方法，利用弹丸在旋转飞行过程中，由于接收点所处位置的不同，接收的短波信号幅值会呈规律性变化，通过提取变化周期利用原有弹载计算机进行数据处理即可测得弹丸转速。本文具体分析了该系统方法的实现原理及关键技术，并对弹上短波天线接收的信号进行仿真。此方法最大的优点是可以解决在转速测量中误差累计的问题。

Research on detection of the rotating speed of a long range rocket projectile based on shortwave signals

The paper presents a method for measuring the rotating speed of a long range rocket projectile by using short wave signals.During a rocket projectile flying and rotating,the ampli- tude of the received short wave signal changes regularly with the difference of the received place.The rotating speed of the rocket projectile can be obtained by extracting the variational periods.The paper analyzes the working principle of the method and the key technology,and simulates signals transmitted from shortwave antenna...
