摘要
舰载雷达在工作时采用抑制海杂波技术,能有效的减小海杂波对海上目标检测带来的干扰。本文以海杂波的数学统计模型为基础,系统分析了不同海情情况下适用的抑制海杂波的方法。自适应海杂波滤波器和恒虚警检测主要针对各海情的海杂波抑制,提高分辨率和MTI技术适用均匀分布的海杂波抑制。通过系统分析各种海杂波抑制方法的选择和使用条件,为舰载雷达海杂波背景下的信号处理领域提供了重要的理论依据。
The shipboard radar can effectively reduce the disturbance caused by sea clutter through suppressing sea clutter at work. Based on the mathematical statistic model of sea clutter, this paper systematically analyzes the methods of suppressing sea clutter under different sea conditions. The adaptive sea clutter filter and constant false alarm detection are suited to all kind of sea clutter condition, while improving the resolution and MTI technique are fit for uniform distribution of sea clutter suppression. The systemic analysis of detection methods and configuration conditions provides the important theoretical basis for signal processing for shipboard radar.
