大面积多周期伪随机序列扩散体群的一种优化布置方案

A prediction method of layout plan of large area and periodical pseudorandom sequence diffusers

伪随机序列扩散体具有良好的扩散效果,但是大面积周期布置时会在扩散方向产生大量旁瓣。为了消除这些旁瓣,并得到符合使用者要求的扩散声压响应曲线,本文提出一种实现伪随机序列扩散体群大面积最佳布置方案的布置方法。

Pseudorandom sequence diffusers provide good scattering, but when multiple periods are used, the diffusion pattern will be narrowed into specific directions. This paper presents a method of layout plan of large area pseudorandom sequence diffusers to cut down the diffuse peaks and to meet user's demand.
