Phased TT&C Technology(Ⅵ):Time-varying Filtering Characteristics of Phased Array and Its Impact on Communication Performance
摘要
Abstract
Aperture transition effect is a special problem of phased array.In response to this problem,the author derives its amplitude/phase frequency characteristics and proposes to make phased array be equivalent to as a"time-varying filter"in the transmission link to form a phased array band-limited communication system.Then,some mature theories of communication systems can be used to study its main performance indicators such as effectiveness,reliability,and adaptability.As an example,the author analyzes the additional errors caused by it and its equivalent carrier to noise ratio deterioration and other reliability indicators,and provides improvement measures.关键词
