| Abstract: |
| The measured values from the isolation of seeker installed with a centroid offset commonly have bias. A data correcting method of the measurement isolation values of seeker is presented.The mathematical model of seeker installed on the turntable with a centroid offset is established. The angle-velocity errors caused by the centroid offset installation are derived for analyzing the influence of the angle-velocity errors on the measurement values of seeker. Finally,a revising method is given. Computer simulation and test result verify the feasibility of the proposed method. It is instructive for practical project in which missile tracks surface targets. |
