A study on synthetic aperture sonar movement compensation based on displaced phase center algorithm 基于位移相位中心算法的合成孔径声纳运动补偿研究
The result demonstrates that the variable phase center of fish antenna is much more steady than the lpda in the main beam 计算结果表明鱼骨天线在主波束相当宽的范围内,其可变相位中心的稳定度要优于对数周期偶极子天线。
This paper is worked to solve the phase center of the directional antenna , accordingly to giving some references for the interception and direction - finding system 本文是为了解决定向天线的相位中心问题,为侦测合一系统设计提供参考而展开研究的。
The dissertation also discusses a kind of improving algorithm of dpca : adaptive displaced phase center antenna ( adpca ) , indicate the adpca can be used in distributed space - borne sar 5 .对dpca的改进技术( adpca )进行了探讨。通过分析,说明了adpca技术在分布式星载sar系统中应用的可行性。
Moreover , the fish antenna is often used in the detection system . the variable phase center of the antenna is calculated which contain vertical polarization and horizontal polarization 另外,本文对在侦收站中常用的鱼骨天线在水平极化和垂直极化两种状态下的可变相位中心作了深入地研究。
In the interception and direction - finding system , the phase center of the antenna is very important to the direction - finding , however , the phase center of directional antenna is few studied in the home and overseas 在侦测合一系统中,天线系统的相位中心对于系统测向有着至关重要的作用,但是目前国内外对于定向天线的相位中心研究的非常少。
The mathematical expression , which is used to calculate the variable phase center based on the mom , is derived first in the paper . it is proved that the variable phase center of the lpda is not superposition in the e - plane and the h - plane 文中采用矩量法,首次导出了基于矩量法多分段计算可变相位中心的表达式,证明了侦测合一系统中常用的对数周期偶子天线( lpda )在e面和h面的可变相位中心不重合。
