| 摘 要： | 为解决多普勒扩展杂波对天波超视距雷达（OTHR）慢速舰船目标检测的遮蔽问题,分析了多普勒扩展杂波的成因,推导了多输入多输出（MIMO）体制下一种天波雷达信号处理模型;将该模型与数据阻塞预处理相结合,提出了一种抑制天波雷达多普勒扩展杂波的方法.理论分析与仿真结果表明,该方法能够有效抑制多普勒扩展杂波,减轻其对天波雷达慢速舰船目标检测的影响.

| Abstract: | To solve the problem of spread-Doppler clutter shielding the slow ship detection of over-the-hori-zon radar（OTHR）,this paper analyzes the causes of the spread-Doppler clutter,derives a signal processing model for the MIMO OTHR,and presents a method for mitigating the spread-Doppler clutter of the OTHR by combining this model with data jamming preprocessing,Theoretical analysis and simulation show that this method can be available for suppressing the spread-Doppler clutter and mitigating its impacts on the slow ship detection of the OTHR. |
