以地基分布式有源雷达组网系统为讨论对象,在具体分析了4种系统定位误差的相互关系的基础上,给出了一种 基于ECEF转换法的系统目标综合定位精度评估模型,并利用典型的雷达参数,对2D与3D混合的雷达组网系统的实际目标 综合定位精度进行了仿真和对比分析,得到了一些对雷达组网系统的实际部署优化处理有参考价值的结论。 (The land-based distributed active radar network system is taken as discussion object.On the basis of the concrete analysis of the interrelation among four sorts of locating errors, a model of evaluating the integrated system locating precision is put forward. By using the typical radar parameters, the simulation a of the actual integrated locating precision of 2D/3D hybrid radar network systems are done. Conclusions that are helpful for optimization of radar network disposition are obtained. )
