首先对相干多输入多输出(MIMO)体制在天波超视距雷达中的应用可行性和典型应用场景进行了研究,分析了对海探测场景下MIMO体制的主要优点;然后,提出了兼容MIMO和相控阵体制的实现架构,给出了MIMO处理流程并基于典型的随机二相码正交波形集开展了分析;最后,设计了验证试验和效能评估方法,验证了MIMO体制应用的可行性和有效性。

This paper discusses the feasibility and typical application of coherent multiple-input-multiple-output (MIMO) system in sky-wave over-the-horizon radar, and analyzes the main advantages of the MIMO system in the sea targets′ detection. On this basis, the paper proposes the practical framework compatible to MIMO and the classical phased array, and presents the MIMO processing scheme. An orthogonal waveform set of typical random phased code has been analyzed and applied. Finally, a kind of experiment and performance estimation method has been proposed to demonstrate the feasibility and availability of MIMO system for OTHR.
