所解决的问题是，高频（HF）单站点定位（SSL）使用线性阵列，其中感兴趣的信号传播超过视线通过天波模式。本文提出了一种新的定位方法，利用多路径来解决的“圆锥”模糊线阵列。这是第一次为使用线性阵列执行有意义的HF-SSL提供了可能性。该方法同样适用于基于二维孔径的传统高频SSL系统。在这种情况下，优点是减少估计误差，而不是解决模糊性。用高频源上已知地面真实值的实验数据验证了该方法的有效性。
The problem addressed is that of high frequency (HF) single site location (SSL) using a linear array, where the signal of interest propagates beyond the line of sight via the sky-wave mode. The paper proposes a new geolocation method that exploits multipath to resolve the “coning” ambiguity in a linear array. For the first time, this opens up the possibility to perform meaningful HF-SSL using a linear array. The proposed method is also applicable to traditional HF-SSL systems based on two-dimensional apertures. In this case, the advantage is reducing estimation errors as opposed to resolving an ambiguity. Experimental data with known ground truth on a HF source is used to validate the method.
