摘要
An ahead-looking sonar can be used in the underwater environment for obstacle avoidance and observation of seafloor features. Single frequency, split-aperture sonar systems are useful in these applications, but a wideband monopulse sonar is preferable because of its performance characteristics. Previous theoretical studies of this type of sonar have been limited to very simple seafloor geometries and have scarcely addressed the response to objects in the ocean volume. A time-domain simulation which lends itself to the study of complex ocean environments, including complex seafloor shapes and suspended objects, has been developed. This simulation is used to study the response of a monopulse sonar to the presence of rigid cylinders near the seafloor. An acoustic scattering center model is developed to represent the cylinders, and several examples are presented and discussed. © 1990 IEEE
