深入分析了多途效应的起因,对声波干涉起伏进行了建模,分别仿真计算了单频和三频制下的声传播起伏,并对仿真结果进行对比分析。仿真结果表明:多频制方法对声起伏具有明显的抑制功能,可提高声自导系统的作用距离。
The cause of multipath effect is deeply analyzed, and the acoustic wave undulation is modeled. The acoustic propagation undulations in single-frequency and tri-band systems are simulated respectively. The simulation results are compared and analyzed. The simulation results show that the multi-frequency control method can significantly reduce the acoustic fluctuation and improve the working distance of the acoustic self-guided system.
