前言由于引信从来都是做为武器军械系统中一个极为机密的重要部分而出现的。因此与弹上其他无线电设备不同,引信系统从未以普通产品的形式出现在商业市场。各国对引信研制的情况,虽不能说是守口如瓶,但也是所露甚微,一般杂志上所公开发表的引信资料极少。即便是在某些刊物上(如AD报告专刊等)有所发表,也往往是十几年前的水平。例如,对于噪声雷达引信美国在50年代末期就已进行大量的研制,并申请专利,但直到70年代才公开 Foreword Since fuzes have always been an extremely secretive and important part of the weapon ordnance system. Therefore, unlike other radio equipment on the bomb, the fuze system has never appeared in the commercial market as an ordinary product. The development of fuze in various countries, although it can not be said to be tight-lipped, but it is also a mere disclosure, published in the general journal fuze information is minimal. Even in some publications (such as AD report, etc.) published, it is often a dozen years ago. For example, for the noise radar fuze, the United States in the late 1950s had a lot of research and patent application, but it was not disclosed until the 1970s
