稳定跟踪平台陀螺噪声及滤波去噪方法

摘要

The internal frame velocity stabilization loop of the airborne stabilization and tracking plat-form is modeled based on the mechanism analysis .Studied the impact of gyro noise on platform system , the analyzing result indicates that the gyro noise would cause the jitter of the line of sight and slow drift on angle and have a great influence on stable precision and tracking accuracy of platform system .Analyzed the gyro noise data and studied the Kalman filter method to denoise the signal of gyro noise ,then the sim-ulation results show that the Kalman filter method could achieved good performance on denoise the signal of gyro noise .%　　在机载稳定跟踪平台中对内框架速率稳定回路进行机理分析并建立数学模型，分析了陀螺的输出噪声对平台系统的影响，结果显示陀螺噪声会引起稳定平台输出轴的抖动和角度漂移并对平台系统的稳定精度与跟踪精度都有很大影响。分析了陀螺噪声数据及基于卡尔曼滤波的去噪算法并分析滤噪效果，结果表明卡尔曼滤波效果明显，是理想的陀螺噪声滤波器。
