实际防侦听的战场通信设备的研制是微电子学可以做到的“奇迹”之一。当然,任何码子迟早总能被破译,但在小范围的战术行动中时间总是不足的。新的、小型化的、几乎瞬时起作用的加、解密器通常都使用数字计算机技术,它们使得话音通信对任何侦听的敌人来说都是不可懂的。可以买到各种各样这类产品,它们由各种规模的公司生产,这些公司大的如生产多种电子产品的Marconi和Racal公司,以及一些小的这方面的专业化公司。 * * * 瑞典菲利蒲电子工业AB公司,国防电子学分部 Phi1ips电子工业公司生产的9 EC750/755是一对数字话音加密系统,它能
The actual anti-listening battlefield communications equipment development is one of the “miracles” microelectronics can do. Of course, any code can always be deciphered sooner or later, but time is not always enough in small-scale tactical operations. New, miniaturized, almost instantaneous add-ons and decryptors often use digital computer technology that makes voice communications incomprehensible to any listening enemy. A wide variety of these products are available, made by companies of all sizes, such as Marconi and Racal, which make a wide range of electronic products, and some small specialized companies in this area. * * * Philips Electronics AB AB, Defense Electronics Division Phi1ips Electronics Corp. 9 EC750 / 755 is a digital voice encryption system that enables
