为了控制火箭弹的飞行来减小射弹散布和增加射程,需要实时测量其滚转角。本文提出了应用四只相邻成直角安装的加速度传感器来组成加速度传感器阵来对火箭弹的滚转角进行测量。通过运算分析加速度传感器的输出参数,并应用相关的器件对获得的参数进行一系列信号处理来消除重力加速度,从而得到火箭弹瞬时的滚转角。最后,分析误差结果,得出设计算法的可行性。 In order to control the rocket flight to reduce the projectile dispersion and to increase the range, the roll angle needs to be measured in real time. This paper presents the application of four adjacent acceleration sensors mounted at right angles to form an array of acceleration sensors to measure the roll angle of the rocket. By analyzing the output parameters of the accelerometer and applying a series of signal processing on the obtained parameters to eliminate the gravitational acceleration, the instantaneous roll angle of the rockets can be obtained. Finally, the error results are analyzed and the feasibility of the design algorithm is obtained.
