In order to make an anechoic chamber operate similarly to ideal OATS, various design methods of the anechoic chamber have been studied. Without changing of RAM and major structural design of the rectangle anechoic chamber, we propose a method of automatically designing the shape of a slanted wall anechoic chamber by applying the PSO to 3D deterministic ray tube method. The 3D Deterministic Ray Tube method enables efficient and fast calculation of the electric field in any slanted wall anechoic chamber. The optimized slanted wall anechoic chamber has very good performance for NSA, sVSWR compared to the general rectangle chamber.

使用3D确定性射线管方法自动设计斜壁消声室

为了使消声室与理想的 OATS 类似地工作，已经研究了消声室的各种设计方法。在不改变RAM和矩形消声室主要结构设计的情况下，我们提出了一种将PSO应用于3D确定性射线管方法自动设计斜壁消声室形状的方法。3D 确定性射线管方法可以高效快速地计算任何斜壁消声室中的电场。与一般矩形暗室相比，优化的斜壁消声室在 NSA、sVSWR 方面具有非常好的性能。
