杭州机场“电子围栏”技术可实现半径10公里防控

2017-05-20 15:26:12   新华社

新华社杭州5月20日电(记者魏一骏)记者日前从杭州机场方面获悉,一项针对机场防控无人机的最新现场测试显示,一套干扰系统建立的“电子围栏”可实现半径10公里全方位防控,确保机场净空保护区的飞行安全。

近年来,无人机在航拍、农业、测绘等领域作用日益显现,但同时也屡闯空中“禁区”。业内人士介绍,如果重量为10千克的无人机与飞行速度每小时900公里的飞机相撞,冲击力将达到125万牛顿,其能量不亚于一颗小口径炮弹,会直接洞穿机体,造成机毁人亡的惨剧。

为此,杭州机场制定完成了《杭州萧山国际机场低、慢、小航空器(无人机)防控工作方案》。

杭州机场相关负责人介绍,防控方案中,“电子围栏”技术成为推进无人机干扰系统的重点。该技术采用无线电探测技术切断无人机与遥控器的信号连接,使无人机无法接受指令并按自带GPS系统原路返回地面,实现电子干扰。

杭州机场相关负责人再次提醒,从事通用航空飞行活动的单位、个人,未经批准擅自飞行、未按批准的飞行计划飞行、不及时报告或者漏报飞行动态、未经批准飞入空中限制区域和空中危险区域的,将由有关部门按照职责分工责令改正,给予警告;造成重大事故或严重后果的,依照刑法追究刑事责任。
