利用无线电引信测量长路径弹丸转速的应用研究

利用HP8566B频谱分析仪和预选器组成高灵敏度的动态接收测量系统，并用配备竖环天线的无线电引信作为发射设备进行转速测量，研究利用无线电引信弹道监测原理进行长路径弹丸转速的测量方法和工程实现途径，该测量系统经过实际使用，证明系统是稳定，可靠的，这种方法的最大优点是弹上不需研制任何新的设备，对弹丸本也不需做任何结构上的改动。

The Application Research on Measuring Long-Distance Projectile Rotating Speed Using Radio Fuse

The method and its engineering realization of measuring long distance projectile rotating speed by means of radio fuse trajectory monitoring principle are developed. High sensitivity receiver measurement system consists of HP8566B spectrum analyzer and preselector. The transmitting equipment is made up of ring shaped antenna radio fuse. It has been proved by practical use that the measurement system is stable and reliable. The advantage of the method is as follows: new equipment in shell is not necessary to be developed, and the projectile itself need not be modified.
