A model for narrow‐band surface reverberation is formulated, implemented on a general‐purpose computer, and validated. At each instant of time, the model divides the ocean surface into an annulus of incremental sectors. The time and frequency characteristics of the reverberation from each sector are modeled by passing Gaussian random noise through narrow‐band digital filters. Spherical spreading, absorption, and nonisovelocity effects are included in the model. The validation is accomplished by statistically comparing the model’s output with experimental data collected in an open‐water environment.
