Considering the time-varying movement of the canvas constituting a vibrating intrinsic reverberation chamber (VIRC), the optimization of the stirring process of such facility is not trivial. Indeed, this task requires reliable and accurate metrics able to state if a given modification of the stirring process will increase or decrease the VIRC performance. This article presents a fast and accurate relative method based on the K -factor metric. For each stirring configuration to be assessed, the scattering parameter measurements that are required typically last less than a minute. Used in a recently installed VIRC, the method has led us to optimize each implemented stirring process (fans installed outside the VIRC and two motors pushing the canvas) and to greatly increase the VIRC performance when all these processes are combined together.

使用散射参数测量优化振动固有混响室的搅拌过程

考虑到构成振动固有混响室（VIRC）的画布随时间变化的运动，优化此类设施的搅拌过程并非易事。事实上，这项任务需要可靠且准确的指标，能够说明搅拌过程的给定修改是否会提高或降低 VIRC 性能。本文提出了一种快速、准确的基于K 因子度量。对于要评估的每种搅拌配置，所需的散射参数测量通常持续不到一分钟。该方法在最近安装的 VIRC 中使用，使我们能够优化每个实施的搅拌过程（安装在 VIRC 外部的风扇和推动画布的两个电机），并在所有这些过程结合在一起时大大提高 VIRC 的性能。
