Abstract
The Parabolic equation method with split‐step Fourier algorithm models cw transmission in range‐dependent channels. For some applications, it is desirable to predict the impulse response of the channel. The Parabolic equation code has been applied to each cw component of the Fourier‐decomposed transmitted signal and the pulse response resynthesized at the receiver. This method was used to study the transmission in the Arctic ocean [Kutschale and Tappert, J. Acoust. Soc. Am. Suppl. 1 62, S18 (1977)]. We model range‐dependent bottoms and profiles for shallow water sound transmission in the Florida Straits. Pulse responses are given for surface ducts and also for SOFAR propagations. Results are compared with the range‐dependent ray theory. Pulse responses near caustics are examined. [Work supported by ONR.]
