| 摘 要： | 分析了在车载平台惯导陀螺仪控制角速率的实际测量中,由于油机启动、人员走动、风扰等低频干扰的存在,很难将有用信号和干扰信号区分开导致的寻北误差这一工程实际问题.介绍了小波理论这种新的信号处理技术,将其应用于控制角速率测量处理中.试验结果表明,在扰动条件下,提高了平台惯导的寻北精度,有重要的理论意义和工程实用价值.

| Abstract: | It is a difficult engineering problem that useful information is distinguished from low-frequency disturbed signals in gyroscope measurement of controlling rotation rate due to low frequency disturbance such as engine on,personnel ambulation and wind,inducing azimuth determining error.A new signal processing method is proposed,and it is used to process the measurements of controlling angle rate.Experimental results indicate that this method improves azimuth determining accuracy under the condition of distur... |
