M. Wakihara,H. Ikuta,Y. UchimotoP) and raypath plot. The sun warms the surface waters generating a gradient of decreasing temperature with depth to about 100 ft depth. Thereafter temperature slowly increases with depth. Sound speed increases with water temperature causing the acoustic wavefront to refract downward near the surface同音 发表于 2025-3-27 16:10:22
Ambiguity Functions,nge (r), delay (τ), velocity (v), and Doppler (ø, β) are related by . and . or . for the narrow and wideband representations respectively and a monostatic line of sight geometry. In this context, an uncertainty function (UF) is a complex two dimensional function and its associated real ambiguity fun打折 发表于 2025-3-27 18:53:33
