1.前言为了进行高精度跟踪,运动物体上所装备的跟踪装置,必须排除干扰,稳定跟踪轴。作为稳定跟踪轴的方法,可以考虑如下三种方案。(1)稳定载体的姿态,以稳定后的载体轴为基准,用载体轴与跟踪轴的误差信号来稳定跟踪轴。(2)在跟踪轴上安装惯性传感器,用惯性基准与跟踪轴的误差信号来稳定跟踪轴。(3)在二自由度或三自由度陀螺上安装跟踪系统,利用陀螺转子的陀螺惯性来稳定跟踪轴(陀螺架方式)。在上述方案中,(1)在飞机上、(2)在比较大的跟踪装置上广泛使用。
1. Preface In order to carry out high-precision tracking, moving objects equipped with tracking devices, you must rule out interference, stable tracking axis. As a method of stabilizing the tracking axis, the following three solutions can be considered. (1) Stabilize the attitude of the carrier, stabilize the tracking axis with the error signal of the carrier axis and the tracking axis based on the stabilized carrier axis. (2) Mount the inertial sensor on the tracking axis and stabilize the tracking axis using the error signal of the coasting reference and tracking axis. (3) Install the tracking system on a two-DOF or three-DOF gyro, and use the gyro inertia of the gyro rotor to stabilize the tracking axis (gyro frame method). In the above scenario, (1) on aircraft, (2) is widely used on larger tracking devices.
