基于船载合建站条件下的角度标校新方法

准确的角度标校是船载测控系统精确跟踪测量目标的必要条件,测量船如何在海上动态条件进行跟踪测量设备的标校,是确保海上测控任务圆满完成,特别是解决设备故障后需要解决的关键问题。根据船载合建站的特点,提出一种新的无塔角度标校方法,即在2套跟踪测量系统同时工作的模式下,在一套跟踪测量系统稳定跟踪信标球的同时,另一套跟踪测量系统进行标校,通过稳定跟踪目标电零点和加偏跟踪等方式,对跟踪测量系统跟踪通道的相位和幅度进行精确校准。该方法机理清楚、操作简便,已经在多次卫星测控工程实践中得到了验证。

A New Method of Angle Calibration Based on Shipborne Syncretic Station

Accurate angle calibration is a necessary for a ship-borne TT＆C system to track and measure aircraft. How to calibrate the angle of a tracking radar is a key to guarantee the success of TT＆C mission during a long-time sea duty, especially when the device problem was resolved. This paper puts forward a new method of angle calibration independent of tower according to characteristic of the ship-borne syncretic station. That is to calibration the other tracking system when a tracking system tracks a air balloon carded a cooperated beacon under the coinstantaneous mode of two tracking and instrumentation system. This idiographic method is calibrating the tracking channel phase and amplitude via such modes as direct track and given biasing voltage track. The method, due to its clear mechanism and easy operation, has been verified in many satellite TT＆C engineering projects.
