Evaluation Method on Multi-stage Bayes Information Fusion for Scatters HWIL Simulation

为对射频半实物仿真系统中复杂体目标进行仿真,介绍了复杂体目标多散射中心从外场数据、数学仿真数据、半实物仿真数据三阶段评估等效性框架,分别利用作为阶段的验前信息进行传递,设计了基于可信度的多阶段Bayes信息融合的多散射中心半实物仿真等效性评估。在基于外场数据和数学仿真数据2个阶段的验前信息,通过信息融合Bayes理论,得到并比较了各阶段数据重构度平均值,获取可信度更高的半实物仿真等效性评估值。

In order to simulate the complex 3D target in the RF HWIL(hardware in the loop simulation) system, the equivalence framework of multiple scattering centers of complex 3D target for three stages of outfield test data, mathematics simulation data and HWIL data are introduced. Using the pre-test information as each stage for transmission, evaluation method is designed by multi-stage Bayes information fusion for HWIL simulation. Based on prior information of outfield test data and mathematics simulation data, by using Bayes information fusion theory, the average data reconstruction of each stage is obtained and compared and high reliability for HWIL simulation can be achieved.
