为解决陀螺测量高旋弹角运动参数的问题，在对高旋弹的运动特性进行分析研究的基础上，建立陀螺测量角运动参数的数学模型，提出基于小波变换和陀螺的高旋弹角运动参数测量方法。先对基于俯仰轴安装的陀螺测量数据进行小波滤波，得到近似正弦曲线的耦合角运动曲线，再利用正弦曲线过零点和极值点计算弹体俯仰角速度、滚转角速度及滚转角。实验证明，所提方法能有效测量高旋弹的俯仰角速度、滚转角速度和滚转角，测量结果精度较高。

For the issue of measuring the high?spin projectile angular motion parameters with low?range gyro, an a?nalysis of high?spin projectile motion characteristics was conducted. A mathematical model of measuring angular mo?tion parameters using a low?range gyro was established and a measurement method of the angular motion parameter of high?spin projectile was proposed based on wavelet transform and a low?range gyro. Based on the wavelet filter processing of the measured data from the low?range gyro installed along with the pitch axis, the coupling angle mo?tion curve similar to sinusoid was obtained. The motion parameters including the pitch rate, roll angle rate and roll angle of the high?spin projectile were also estimated using the zero?crossing and extreme points of sinusoid. The ex?periments showed that the proposed method can effectively calculate the above?mentioned motion parameters of high?spin projectile, with the accuracy of 3. 6% for the pitch rate, 1‰ for roll angle rate, and 2° for roll angle.
