1.
This paper introduces the component and the operation principle of the jammer using DRFM,and analyzes the emergence of frequency spot error and spurious signal,and their influence on the jamming noise.
介绍了DRFM干扰机的组成和工作原理,并分析了瞄频误差和寄生信号的产生以及它们对干扰噪声的影响。
2.
Aimed at the effect which the spurious signal of phase quantization DRFM has on the design of jammers,the spurious signal power variation on the condition of different quantized bits is analyzed to provide DRFM analysis and design with a reference.
针对相位量化数字储频寄生信号对干扰机中数字储频设计的影响,分析了量化比特数不同时寄生信号的功率变化,为数字储频的分析和设计提供一个参考。

黑斑
黑斑 证名。多指外感热病发斑色黑之证。巢元方《诸病源候论》指出:时气病重证可现黑斑,认为是“十死一生”之证。《温热经纬·叶香岩外感温热篇》:“黑斑而光亮者,热胜毒盛,虽属不治,若其人气血充者,或依法治之,尚可救。”选用化斑汤、升麻葛根汤、玄参升麻汤、黑膏、黑奴丸等方。参见斑条。
