一、引言近七几年来,日本的导弹、火箭、卫星等空间技术也得到了迅速的发展。随之而来的外测系统的研制也同时进行,其成就是显著的。特别是弹载应答机,其电气性能和美帝六十年代末的产品比较虽拜下风,但在结构工艺方面确有独特之处,下面介绍一种日本的典型脉冲应答机。 I. INTRODUCTION In recent seven years, Japan’s space technology such as missiles, rockets and satellites has also been rapidly developed. Followed by the development of external measurement system also conducted at the same time, its success is significant. Especially the bomb transponder, the electrical performance and the United States the late 1960s compared to the product comparison, but in the structural process is indeed unique, here is a description of a typical Japanese pulse transponder.
