船载测量雷达稳定回路作用分析

Analysis of Stabilization Loop's Impact on Shipborne TT&C Radar

分析了船载测量雷达陀螺稳定回路的作用机理,以及稳定回路作用前后雷达跟踪稳定性。用Matlab对稳定回路作用前后跟踪回路进行了仿真,对分系统误差分量和随机误差分量进行了跟踪精度分析,并通过两次测量任务数据处理结果的比较,证明船摇较小时,加入稳定回路会造成跟踪精度的降低。

The mechanism of shipborne TT＆C radar＇s stabilization loop composing of gyroscope is analysed,as well as the tracking stability before and after applying the loop. The tracking loop before and after applying stability loop is simulated with MATLAB. The tracking precision of Subsystem error component and the random error component is analysed. Through comparison of two tracking missions data processing result, it has proved that when ship rocking scale is very small, the tracking precision will be reduced when the stabilization loop works.
