摘要：

针对电离层动态性对天波超视距雷达检测概率和探测精度的影响, 构建了一种基于分布式多输入多输出(multiple input multiple output, MIMO)体制的完整天波超视距雷达仿真系统。通过搭建模块化仿真框架和可视化展示界面, 集成电离层数据接口, 实现信号发射、电离层反射、信号接收、信号处理和目标检测的功能。最后对雷达系统探测性能进行评估, 利用仿真实例验证了整体雷达仿真系统的可行性。该系统的实现对于分布式MIMO天波超视距雷达的性能评估、布站优化、装备发展论证具有一定的工程指导意义。

Abstract:

Considering the effects of ionospheric dynamics on the detection probability and detection accuracy of sky-wave over-the-horizon radar, this paper develops an integrated distributed multiple input multiple output (MIMO) sky-wave over-the-horizon radar simulation system. By building a modular simulation framework and a graphical user interface, and integrating the ionospheric data interface, the functions of signal transmission, ionospheric reflection, signal reception, signal processing and target detection are realized. Finally, the radar detection capabilities are evaluated and the feasibility of the entire radar simulation system is verified by simulation examples. This implemented simulation system can help the performance evaluation, optimization of site deployment, and development of distributed MIMO sky-wave over-the-horizon radar.

Key words: distributed multiple input multiple output (MIMO) radar, sky-wave over-the-horizon radar, signal processing, simulation system
