针对传统的基于概率分布假设的小样本电子装备等效辐射功率估计风险较大的问题,提出了基于小样本的电子装备等效辐射功率的模糊扩散估计方法。介绍了等效辐射功率的测试过程,基于模糊信息扩散原理进行了等效辐射功率母体概率密度函数的估计;以某电子干扰装备的等效辐射功率估计为例,对其进行了模糊扩散点估计和给定置信度的区间估计。实例分析结果表明:该方法简单、可行,估计结果稳健性较好。

Aiming at the great risks on traditional estimation for Equivalent Radiated Power( ERP) of electronic equipment based on small samples of probability distribution hypothesis,a fuzzy information diffusion estimation method for ERP of electronic equipment based on small samples is proposed. The test process of ERP and the estimation method of overall probability density function of ERP based on fuzzy information diffusion theory are introduced. Taking the estimation of ERP of a certain electrical equipment for example,the point estimation and interval estimation under certain confidence levels are obtained.Example analysis results show that the method proposed is feasible and effective,and the estimation result is of fine robustness.
