中国大批装备F22克星 乌克兰帮大忙

资料图:被动雷达DWL-002。
【环球军事报道】据俄罗斯之声网站9月30日报道中国《环球时报》在一篇有关中国无线电电子工 业成就的文章 中谈到了被动雷达DWL-002。可见,专家们早已知道存在的雷达如今被官方媒体“证实”。根据中国以往经验的判断,这或许意 味着, 此种雷达已在军队大范围部署,俄罗斯战略与技术分析中心专家卡申指出。

中国与俄罗斯在两个主要方向应对来自隐身目标的威胁。首先,隐身技术易被普通的主动米波雷达发 现。正如一些 专家指出的那样,几乎是在二战时期制造出的米波低频雷达能够发现隐身飞行器。不过,由于其体积 庞大和准确性 低,西方国家基本停止了对此种雷达的升级改造。

但是,俄罗斯与中国却从未停止过此类工作。隐身飞机的威胁为研发低频雷达提供了新的动力。近2 0年来出现了 新的样品。同时由于电子学和信息技术的进步,科学家克服了这种雷达许多先前被认为是难以克服的 缺点。现代米 波雷达在处理信号时使用的是现代算法。它们具有很高的机动性,虽然它们依然属于非常昂贵和复杂 的系统。米波 雷达JY-27A以及《环球时报》文章中提到的DWL-002都属于这种雷达。至少几个月前就已知道这种雷达的存在。

第二个应对隐身飞行器的方向是被动雷达站。它自身不辐射电磁信号,而是借住外部的辐射源(即目 标本身的辐射 源)来进行探测和定位。现代战机具有复杂的操作和信息交流系统,拥有自己的雷达站,因为通常本 身就是一个辐 射源。苏联和华沙条约组织的一些国家,尤其是民主德国和捷克曾在80年代大力研发此种雷达。当 时以为,一旦 欧洲爆发战争,美国就会千方百计干扰雷达站的工作并用反雷达导弹对其实施打击。而被动雷达就能 防止这种威胁 。

本世纪初中国曾希望购买一批捷克产被动雷达“维拉”,,但在2004年交易因美国的干预而流产 。不过中国也 许在谈判中获得了一些有关这种雷达的技术材料。最终,中国人在乌克兰那里购买到了被动雷达“铠 甲”的样品, 也有可能还获得了一些设计资料。中国人由此获得了进一步开发此种雷达的新的可能,结果研制出了 被动雷达YL C-20以及后来的改版DWL-002。

能说被动雷达以及米波雷达就能消除隐形飞机的威胁吗?未必能彻底消除。说它能够应对隐身战机, 是因为它能把 “神奇的武器”变成普通的威胁。它们的广泛利用可以大大削弱西方国家的进攻潜力。但是只要经过周 密计划和操 作,隐身攻击机和无人机仍然非常有效。
