摘要
提出了一种电磁环境量化分析的新方法.该方法充分考虑了电磁环境信号的极化方式、调制方式,给出了极化因子、调制因子的内涵和定义.基于不同极化方式、调制方式之间影响特性的理论分析和仿真,给出了典型电磁环境的极化因子、调制因子及其变化特性.所得成果为深入研究复杂电磁环境的量化分析和评估方法提供了积极的理论探索.
A method is presented for quantificational analysis for complex electro-magnetic environment. Considering polarization case and modulation approach ade-quately,the connotation and definition of polar factor and modulation factor is giv-en. Based on the theory analysis and simulation of the effect of different polariza-tion cases and modulations, the polar factor and modulation factor in the classic en-vironment and its characteristic variation is given. The study is beneficial to re-search the method of complex electromagnetic environment quantificational analysis and evaluation.
