瑞利衰落信道，是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。这一信道模型能够描述由电离层和对流层反射的短波信道，以及建筑物密集的城市环境。(Rayleigh fading channels, the statistical model of a radio signal propagation environment. This model assumes that after the signal through the radio channel, the signal amplitude is random, ie, the " fading" and the envelope of the Rayleigh distribution. This channel model is able to describe the HF channel reflected by the ionosphere and troposphere, as well as building a dense urban environment.)

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.
