摘　　要：从天波超视距雷达的功能组成与特性出发,就当前天波超视距雷达在系统结构、信号处理等方面存在的问题进行了整理分析,提出了传统天波超视距雷达的改进方法与思路,总结了当前新体制天波超视距雷达的研究进展与热点,对比了两种MIMO(Multiple-Input Multiple-Output,MIMO)体制天波雷达特点,重点研究了基于多输入多输出(MIMO)体制与二维阵列的新体制天波超视距雷达,并对相应关键技术与解决方案进行了深入研究与分析,最后指出了其需要解决的问题与发展方向。On the basis of the function structure and characteristics of skywave over-the-horizon radar（OTHR）,the problems of its system structure and signal processing are addressed and analyzed,and the ameliorated means and thought of the traditional skywave over-the-horizon radar are presented.Then the current research evolvement and hotspots of the new system skywave radar are proposed,and characteristics of the two MIMO（Multiple-Input Multiple-Output）-OTHR are contrasted.The new system skywave radar based on MIMO and 2-D array is illuminated,and some key techniques and approaches way are discussed in detail.Finally the future development direction and follow-up problems are pointed out.
