centimeter wave造句

• To compensate centimeter wave ' s shorting comings such as broad beam and short effective range , a transponder is added in the back of target automotive . this secondary radar measures range in the way of transponding
  为了弥补厘米波波束大、作用距离不如毫米波的缺点，系统在目标车辆的尾部增加了一级转发器，以双机应答的方式测量车距。
• Focused on the realization in engineering practice , this paper discussed automotive anticollision radar ' s function requirement , working principle and system design . through summarizing and analysis of its research and development , the paper proposes a new type of secondary centimeter wave automotive anticollision radar that applied on the expressway
  本文以现有技术的可实现性为出发点，讨论了汽车防撞雷达的性能要求、工作原理和总体设计等相关问题，总结了国内外汽车防撞雷达的研发状况，在此基础上设计了一种应用于高速公路上的应答式厘米波汽车防撞预警雷达。
• Considering that : ( 1 ) radar can achieve its basic application of collision avoidance and warning with the only function of ranging ; ( 2 ) under high speed conditions , radar should have lager effective range than that under slow speed , we designed a new easily realizable automotive anticollision radar , which employs centimeter wave and square pulse amplitude modulation
  考虑到： （ 1 ）核心的测距功能实现以后，雷达已经能够完成基本的防撞预警； （ 2 ）在汽车高速运行的情况下，防撞雷达的最小可测距范围和最大作用距离应比低速状态下大。本文采用了技术成熟，易于工程实现的厘米波脉冲雷达，以单波束辐射的方式测距。
