某型飞机导航误差对CCD稳瞄系统目标搜索域的影响

Influence of Some Aircraft Navigation Error on Target Searching Field of CCD Aiming-Sabilizing System

分析了DG-1型多普勒/GPS组合导航系统,在不同工作方式下导航误差所引起的搜索方位角的误差;讨论了由于搜索方位角的变化引起的搜索域的变化。通过对机理的研究提出了解决办法。

This paper is to analyze that the navigation error generated by the DG-1 DOPPLER/GPS combined navigation system under the different operation modes causes the error of searching azimuth angle and to discuss that the deviation of searching azimuth angle causes the searching field change.Through the study of mechanism,the corresponding solving method is put forward.
