船载雷达伺服系统船摇隔离度静态测试方法

The Static Test Methods of Ship Rocking Isolation Degree for Shipboard Radar Servo System

克服船舶摇摆对船载雷达跟踪的影响是船载雷达伺服系统的特殊性问题,船摇隔离效果的测试和调试需要在雷达试验场进行摇摆台试验或出海以后在船舶生摇时开展,需要耗费大量的人力物力。在对船载雷达伺服系统环路进行建模分析的基础上,文中提出了基于“数引环路”和“自跟踪回路”的两种船摇隔离度静态测试方法。仿真分析和现场试验表明:该测试方法实现简单,便于工程应用。

It is a special problem for the tracking of shipboard radar servo system to isolate ship rocking interference.Currently, the debugging on effect of isolating ship rocking interference is mainly conducted under the condition of swing table test on the radar proving ground or on-site ship rocking on the sea.However,these will cost a mountain of manpower and material resources.In order to achieve the simple test under the static conditions and provide a new method of debugging on the effect of isolating ship rocking interference,the shipboard servo system loop model is developed,two static test methods of digital-guide-loop-based and self-tracking-based are proposed.Through simulation analysis and field test,it is'proved that the approach is ready to implement and convenient for engineering applications.
