摘要
电离层反射传播模式和地波绕射传播模式组合成联合传播模式,对这一新传播模式下的定位方法进行了研究,给出了定位方程,探讨了一种PD差值的计算方法,通过仿真计算说明了该计算方法的有效性,最后基于误差分析理论对定位精度进行分析,了解各误差项对定位距离估值误差所占的权重系数。
For the Hybrid Sky-Surface modes which composed of the ionosphere reflection propagation mode and the surface-wave propagation mode,the algorithm of localization is studied,and the radar range equation is derived.Then a PD difference based algorithm is developed,and its validity is demonstrated by numerical simulations.Finally,the accuracy of the range measurement is analyzed in detail.
