Abstract
In some underwater acoustic waveguides with specially selected sound speed profiles striations or fringes of the interference pattern are determined by a single parameter \beta\ called the waveguide (or Chuprov) invariant. In the present paper it is shown that an analytical description of fringes may be possible in a waveguide with an arbitrary sound speed profile. A simple analytical expression is obtained for smooth lines formed by local maxima of the interference pattern. This result is valid at long enough ranges. It is derived proceeding from a known relation connecting the differences of ray travel times and the action variables of ray paths.
