国际频率登记通报中的短波信号典型发射标识简析

发射标识是一种无线电信号特征描述的国际通用技术指标,使用之处非常广泛。本文介绍了国际频率登记通报(BR IFIC)以及发射标识的含义,并结合实际监测工作,对BR IFIC中登记的短波频率信号的典型发射标识进行了简析。

用发射标识描述设备调制特性的探讨

调制方式是无线电发射信号最重要的技术参数之一,发射标识是ITU通用的一种关于描述射频信号特性的标识方法,两个概念并不相同,本文介绍了在无线电发射设备型号核准工作中,存在用发射标识描述调制方式特性的情况,存在的问题和改进建议。

Research on Radar Emitter Attribute Recognition Method

In order to solve emitter recognition problems in a practical reconnaissance environment, attribute mathematics is introduced. The basic concepts and theory of attribute set and attribute measure are described i n detail. A new attribute recognition method based on attribute measure is prese nted in this paper. Application example is given, which demonstrates this new me thod is accurate and effective. Moreover, computer simulation for recognizing th e emitter purpose is selected, and compared with classical statistical pattern r ecognition through simulation. The excellent experimental results demonstrate t hat this is a brand-new attribute recognition method as compared to existing st atistical pattern recognition techniques.
