摘要:

通过对复杂电磁环境的构成要素多样性及其对装备影响机理差异性的分析，从电磁信号的时域、频域、功率、调制和极化参数入手，提出了一种基于干信比的电子干扰信号度量方法。建立了基于调制匹配系数、极化匹配系数和相对功率强度的度量指标，实现了电磁环境特征、装备技术特点以及电磁环境度量结果的一致性。最后通过仿真计算验证了度量方法的可行性和合理性。

Abstract:

According to the analysis on the variety of complex electromagnetic environment elements and the differences of their effects on the equipments, from the aspects of time, frequency，power，modulation and polarization parameters of electromagnetic signals, a new evaluation method on electronic jamming signal environment based on Signal to Jamming Ratio(SJR) is proposed. A new evaluation index based on modulation matching coefficient, polarization matching coefficient and relative power intensity is established, which achieves the consistency among electromagnetic environment characteristic, equipment technical features and evaluation results. Simulation tests are performed to validate the feasibility and rationality of this method.
