摘　　要：以往对海上目标进行探测都是使用基于双站交叉的超视距无源定位模型技术,导致探测技术的精准度较低。对此,提出一种考虑对流层散射的陆基超视距无源探测技术。首先提取散射信号特征,将接收到的信号视为一个等效散射点对其进行散射。其次构建对流层散射探测模型。最后根据此模型进行超视距无源探测定位目标。实验结果证明了所提方法的可行性。In the past,the technique of beyond visual range passive location model based on cross-over of two stations was used to detect maritime targets,which resulted in low accuracy of detection technology.In this paper,a ground-based over-the-horizon passive detection technique considering tropospheric scattering is proposed.Firstly,the scattering signal features are extracted,and the received signal is treated as an equivalent scattering point for scattering.Secondly,the tropospheric scattering detection model is constructed.Finally,the target is located passively beyond the line-of-sight based on this model.The experimental results prove the feasibility of the proposed method.
