摘要:
The target‐strength characteristics of thin‐walled spheres filled with low‐sound‐velocity fluids have been investigated in the frequency range 100–225 kHz. Theoretical and experimental observations show that the target strength of fluid‐filled spheres is independent of orientation, can be optimized with proper choices of materials, and can be frequency independent. Comparisons of target strength are made with other well‐known passive reflectors.
