甲板坐标系下速率火控射击诸元解算及弹道修正

Firing Data Calculation and Ballistic Correction of Rate Fire-control System based on Deck Coordinates

速率火控系统是在甲板坐标系下解相遇的,它不依赖于导航系统。它与常规火控不同,甲板倾斜的修正不能采用简单的坐标系变换的方式。针对速率火控甲板倾斜修正问题,指出了两种需要进行甲板倾斜修正的情况,推导给出了计算方法,通过原理仿真计算,验证了计算方法的正确性。

The rate fire control system difference from general fire control system by which ,it doesn＇t depend upon navigation system, its hit problem is calculated according to deck coordinates, and the correction of deck tilting can not adopt the simple coordinate transfarmation. In accordance with the correction of deck tilting for rate fire control system,the paper puts forward two instances of deck tilting correction to be needed,and deduces their calculation method. The result of simmulation demonstrates that this method is correct.
