Abstract:

Impulse analysis of the wave equation leads to a convenient approximation for the intensity over a caustic, the field being an interference pattern between two rays. The result, which holds over much of the sonar frequency band, involves only a simple addition to conventional ray-tracing computations. A critical experiment test of the theory is proposed. Author
