摘　　要：　为了对火箭弹实施简易控制,需要实时探测火箭弹滚转角度.本文给出了完整的感应电动势与弹体运动关系,提出了基于记录感应电动势过零点来探测火箭弹滚转角的方法,讨论了探测盲区的形成条件.利用该方法组成的测试系统结构简单,容易实现低成本和高工作可靠性,适合实时测试的要求.To apply a certain simple control to the rocket, the real-time detection of rocket rotation angle is needed. A thorough study of the relation between geomagnetic induction voltage and the movement of the rocket is conducted and a new method for detecting rocket rotation angle is put forward based on the recording of the time when induction voltage reaches zero. The blind area of the detection is discussed also in the paper. With its comparatively simple combination, the method tends to meet the requirement of real-time measurement, high reliability, low cost, and high feasibility.
