基于数据补偿的雷达系统误差估计

建立了多雷达情况下的系统误差观测模型,分析了系统的可观测度,得出系统可观测度和观测数据的空间分布有关的结论.在此基础上,通过数据补偿的方法,产生一个使系统可观测度较大的补偿观测集,用于误差估计.仿真结果显示,使用补偿观测集估计雷达的系统误差,能够获得更优越的估计性能.

Estimation of Radar Systematic Error Based on Data Compensation

In this paper,a systematic error observation model under the condition of multiple radars is established,form which we analyse the system observability resulting in a conclusion that system observablity is related to the distribution of data in space.A new measurement set is produced through data compensation,which gives high system observability to estimate the sysetmatic error.Simulation results show that better performance can be obtained by this set than before.
