摘要
目前,我国的一些雷达测控设备中所使用的机械式手动衰减器,其步进衰减量(10dB)比较大,而且缺乏对信号衰减量的直观显示,也不便于对衰减器进行远程的操作与使用,在应用上具有一定的局限性。针对以上问题,本文提出了一种基于单片机控制的数控衰减器的设计方案,并对该方案进行了设计与实现。
At present, some radar observation and control equipment of our country uses the mechanical type manual attenuator, it step-by-steps the decrement （10dB） quite to be big, moreover lacks to the signal decrement visual display, also is not advantageous for to the attenuator carries on the long-distance operation and the use. has the certain limitation in the application. In view of the above question, this article proposed one kind of the numerical control attenuator based on the Single chip microcomputer, and has carried on the design and the realization to this plan.
