摘要
本文首先介绍扫频接收机在扫描过程中需要控制的各变化量,然后给出了数字扫描控制器组成框图及工作时序,接着详细介绍控制器内部的各个组成部分,并重点说明自动装载数据过程,最后给出了一个应用实例。实例证明,数字扫描控制器可提高扫频接收机扫描过程中的控制精度及扫描速度。
In this paper, firstly, variations of frequency-swept receiver are introduced, which need to be controlled during scanning process. Secondly, a composition diagram and working time sequence of digital scanning controller is proposed. Thirdly, with all details, each constituent in controller is described with emphasis on covering process of automatic date loading. Finally, an application case is presented. Through the case study, it is proved that digital scanning controller can increase controlling accuracy and scanning speed of frequency-swept receiver during scanning process.
