摘要
针对常用导航雷达在检测强海杂波环境下慢速小目标的困难问题,利用扫描间海杂波非相关特性,提出采取提高天线转速的措施和扫描间信号平滑处理技术,从而抑制或削弱海杂波,增强目标信号强度,改善检测性能。实验表明,本方法显著提高了导航雷达在海杂波环境下检测慢速小目标能力。
The detection for slow and small targets in strong sea clutter is difficult for general navigation radar. In this paper, a measure with signal averaging designed to suppress unwanted sea clutter and strengthen wanted signal for achieving targets detection. The measure is increasing the antenna rotation speed. The experiment results show that the proposed measure greatly improves the detection capability of navigation radar for slow and small targets.
