制海权是军事强国现代战争竞争的焦点，文中介绍了DARPA“跨域对海监视与瞄准”、“战术侦查节点”、“九头蛇无人潜水母舰”、“预置式上浮载荷”、“分布式敏捷猎潜”等海战场作战样式研究计划，描述了“反潜持续追踪无人艇”、“竞争环境下目标识别与适应”、“量子传感器”、认知雷达等支撑海战场作战的装备和技术研究项目，从系统功能构成、协同探测维度和智能化三个方面展望了未来海战场预警探测系统发展方向。

Sea dominance is still strong nations' military competition focus. The paper introduces DARPA's marine operation mode research programs, such as CDMaST, TERN, Hydra, UFP, DASH, etc., and depicts equipment and technology research projects supporting marine battlefield, such as ACTUV, TRACE, quantum sensor, cognitive radar, etc. Finally, the paper presents development direction of future marine early warning and detection system in three aspects as system function composition, cooperative operation dimension and intelligent system.
