Today, however, ray tracing codes have fallen somewhat out of favor in the research community, the problem being the inherent (high frequency) approximation of the method which leads to somewhat coarse accuracy in the results.

G. A. M. Vanaerschot,W. E. Colino form a directional receiver in isotropic noise. For this case, there is a gain of signal over noise as compared to a single omni-directional hydrophone because, when “aimed” in the direction of the signal, the receiver picks up all the signal but only a fraction of the isotropic noise.作者: 錯(cuò)誤 時(shí)間: 2025-3-24 03:56 作者: 脖子 時(shí)間: 2025-3-24 08:34 作者: 平淡而無(wú)味 時(shí)間: 2025-3-24 12:59
